sciforum-042490	Dark atom solution for the puzzles of direct dark matter search Timur Bikbaev , Maxim Khlopov , Andrey Mayorov Submitted: 03 Jan 2021 Abstract: Show Abstract	Timur Bikbaev , Maxim Khlopov , Andrey Mayorov	N/A	N/A	Show Abstract
The puzzle of direct dark matter searches can find solution in the model of OHe dark atom, which consists of a stable O^-- lepton core and nuclear interacting (alpha particle) shell of primordial helium nuclei. In this model positive results of DAMA group can be explained by annual modulation of radiative capture of OHe atoms to low-energy bound states with sodium nuclei, which doesn’t take place under the conditions of other underground experiments. The existence of such a low-energy bound state is the key problem of the OHe model of composite dark matter. The complexity of this problem, which has not found a correct solution during last 15 years, requires a consistent approach to its solution. Within the framework of the proposed approach to such modeling, in order to reveal the essence of the processes of interaction of OHe with the nuclei of baryonic matter, a classical model is used, to which the effects of quantum physics and final size of nuclei are successively added. The numerical model of the interaction of the “dark” OHe atom with the nuclei is developed by successive addition of realistic features of quantum-mechanical description to the initial classical problem of three point-like bodies ( O^-- particle, the He nucleus and the target nucleus). The developed approach leads to a numerical model describing the OHe-nucleus system with self-consistent accounting for nuclear attraction and electromagnetic interaction of dark atom with nuclei. The model can prove the interpretation of the results of the direct underground experimental dark matter search in the terms of dark atom hypothesis.
sciforum-038418	Reflecting on design principles in the context of virtual reality learning experiences in astronomy and science education Magdalena Kersting , Jackie Bondell , Rolf Steier Submitted: 04 Oct 2020 Abstract: Show Abstract	Magdalena Kersting , Jackie Bondell , Rolf Steier	N/A		Show Abstract
Virtual reality (VR) technologies have the potential to profoundly transform learning activities in astronomy and science through new forms of perceptual engagement and bodily participation. Since advancements in technology and education drive change in each other, researchers have started to explore opportunities and challenges of using VR in (in)formal learning environments. While research on VR from technology perspectives is extensive, there are relatively few attempts to explore learning-oriented design considerations with VR tools. This study is grounded in the education and public-outreach program of the Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav). The OzGrav-team is an interdisciplinary team of science educators, VR developers, digital artists and astrophysicists that have developed VR outreach programs and school incursions in astronomy. The goal of this study is to identify the experiential affordances of VR in informal learning contexts and to reflect on potential design principles for VR learning experiences in astronomy and science. To articulate issues related to design and learning with VR from multiple perspectives, we unpack critical design decisions of the OzGrav VR learning resources in the form of a dialogue between VR-practitioners and educational researchers. The dialogue draws on primary data from focus-group-interviews with the OzGrav-team. We supplement the dialogue with audio-visual material of a VR experience about the virtual universe. Our findings centre on aspects of collaboration and social interaction in VR-learning, negotiating roles while being an observer/participant in the VR-experience, embodiment in an immersive VR environment, finding a balance between visual richness and accessibility of VR-experiences, limitations of what VR environments can visualize. As the use of VR learning environments gains momentums, our findings contribute to a deeper understanding of the new learning contexts that VR technology can create in astronomy and modern science education.
sciforum-042552	Fermion masses and mixing within a SU(3) family symmetry model with five sterile neutrinos Albino Hernandez - Galeana Submitted: 04 Jan 2021 Abstract: Show Abstract	Albino Hernandez - Galeana	N/A		Show Abstract
Within a broken local vector-like SU(3) family symmetry, we address the problem of quark masses and mixing in a framework with five sterile neutrinos. Heavy fermions, top and bottom quarks and tau lepton become massive at tree level from See-saw mechanisms implemented by the introduction of a new set of SU(2)_L weak singlets vector-like fermions U,D,E,N, with N a neutral lepton. The fermion content also include three right handed neutrinos introduced to cancel anomalies. Therefore, in this scenario light quarks and leptons, including active neutrinos and a light O(eV) sterile neutrino, become massive from radiative loop corrections mediated by the massive SU(3) gauge bosons. We provide a parameter space region where this framework can accommodate the known hierarchical spectrum of quark masses and mixing, the charged lepton masses and simultaneously suppress properly the current experimental constraints on Ko − \bar{Ko} and Do − \bar{Do} meson mixing. We also report the non-unitary, (VCKM)_{4×4} and (UPMNS)_{4×8}, quark and lepton mixing matrices. In addition, we find out that the mass of the SU(2)_L weak singlet vector-like D quark introduced in this scenario may lie within a few TeV's region, and hence within current LHC possibilities.
sciforum-042473	Effects of baryon-antibaryon annihilation in the evolution of antimatter domains in baryon asymmetrical Universe Maxim Yu. Khlopov , Orchidea Maria Lecian Submitted: 02 Jan 2021 Abstract: Show Abstract	Maxim Yu. Khlopov , Orchidea Maria Lecian	N/A		Show Abstract
The mechanisms of baryosynthesis, which involve the three Sakharov's conditions, admit a possibility of nonhomogeneous generation of baryon excess. It may take place in the case of spatial variation of CP violating phase or of the baryon generating field in the early Universe. In the extreme case this nonhomogeneity can lead to the change of sign of baryon excess and formation of antibaryon domains in baryon asymmetrical Universe. Surrounded by the baryon matter, evolution of antibaryon domains is strongly influenced by effect of baryon and antibaryon diffusion to the border of domain and their annihilation. It leads to change of size of domains and antibaryon density in them. The consequence of antibaryon-baryon annihilation at the border of antimatter domains in baryon-asymmetrical Universe is investigated. The successive evolution in the expanding Universe strongly depends on antibaryon density within domain. At low density it is not sufficient to provide separation from cosmological expansion. Such separation can, however, be provided by effects of dark matter, which we briefly discuss. Low-density antimatter domains are further classified with the account for the border interactions. Differently, a similar classification scheme is also proposed for higher-densities antimatter domains. Antimatter domains containing antiprotons and different types of antinuclei are also analyzed within the framework of non-trivial baryosynthesis processes. The antiproton-proton annihilation interactions are therefore schematized and evaluated. The effects of antinuclei-nuclei-interaction-patterns are investigated and taken into account in the analysis of antimatter domain evolution.
sciforum-042480	Inflation, primordial black holes and induced gravitational waves from modified supergravity Sergei V. Ketov Submitted: 03 Jan 2021 Abstract: Show Abstract	Sergei V. Ketov	N/A		Show Abstract
Modified (Starobinsky type) supergravity is used for a viable (unified) description of cosmological inflation and formation of primordial black holes and dark matter in the early Universe. A specific class of models is proposed and investigated in detail. Their observational predictions for primordial black hole masses, dark matter and induced gravitational waves are derived and compared to the current and future astrophysical and cosmological observations. Our approach naturally leads to the two-scalar-field attractor-type double inflation, whose first stage is driven by Starobinsky scalaron and whose second stage is driven by another scalar field which belongs to a supergravity multiplet. The scalar potential and the kinetic terms are derived, the vacua are studied, and the inflationary dynamics of those two scalars is investigated. We numerically compute the power spectra and find the ultra-slow-roll regime leading to an enhancement (peak) in the scalar power spectrum. This leads to an efficient formation of primordial black holes. We estimate their masses and find their density fraction as part of dark matter. We show that our modified supergravity models are in agreement with inflationary observables, while they predict the primordial black holes masses in the range between 10^16 g and 10^20 g. In this sense, modified supergravity provides a natural top-down approach for explaining and unifying the origin of inflation and the dark matter in the form of primordial black holes.

S8. The Universe of Andrei Sakharov

In 2021, we will commemorate the 100th anniversary of the birth of Andrei D. Sakahrov, and UNESCO has nominated this year A.D. Sakharov year. The paper "Cosmoparticle Physics as Cross-Disciplinary Science" was the last in the list of Sakharov's publications, so studies of the fundamental relationship of cosmology and particle physics further developed his scientific legacy.

Sakharov conditions in baryosynthesis, Sakharov oscillations in CMB, and Sakharov enhancement in dark matter annihilation are but a few examples of A.D. Sakharov’s legacy in the modern theory of the Universe. The aim of this session is to discuss the place and prospects of the development of Sakharov's legacy in studies of the mutual relationship of the bases of modern particle physics and cosmology, as well as the nontrivial features of its indirect physical, cosmological, and astrophysical probes. Such features involve but are not limited to models of the very early Universe and their observational signatures, physics of dark matter, and its direct and indirect probes, as well as to a wide range of models beyond the standard models of particle physics and cosmology and their effects.

Keywords: cosmology; particles physics; astroparticle physics; cosmoparticle physics; BSM models; dark matter; inflation; baryosynthesis; supergravity; extra dimensions

S9. Teaching Relativity and Modern Physics in General

General relativity describes the interplay between the geometry of space-time and its matter and energy content; together with quantum mechanics, on which the standard model of particle physics is based, they represent a best understanding of our universe and of fundamental interactions. Both theories have their roots in the works published by Einstein in his miraculous year, 1905: accordingly, we may refer to modern physics as Einsteinian physics. General relativity and quantum mechanics, besides having an outstanding importance for science, influence our everyday life because of their impact on our technology, such as, for instance, GPS and mobile devices. Despite all this, the Newtonian concepts of space and time, which are in conflict with the modern physics approach, are still largely taught in schools worldwide.

In this session, we will discuss the necessity and possibility of teaching Einsteinian ideas across Years K–12, to give students a better awareness of the modern understanding of our universe. Contributions addressing good practices in teaching modern physics from primary to secondary schools are welcomed.
