Baryon asymmetric Universe from spontaneous CP violation by Kohei Fujikura, Yuichiro Nakai, Ryosuke Sato, Masaki Yamada

“…In this study, we show that a supersymmetric NB mechanism can naturally accommodate the Affleck-Dine (AD) baryogenesis within a CP-invariant Lagrangian. The model provides flat directions associated with new heavy quarks. …”

PBH-infused seesaw origin of matter and unique gravitational waves by Debasish Borah, Suruj Jyoti Das, Rome Samanta, Federico R. Urban

“…Thence, a low-frequency GW feature related to DM genesis and detectable with a pulsar-timing array must correspond to a mid- or high-frequency GW signature related to baryogenesis at interferometer scales.…”

Probing leptogenesis at future colliders by Stefan Antusch, Eros Cazzato, Marco Drewes, Oliver Fischer, Björn Garbrecht, Dario Gueter, Juraj Klarić

“…The measurement of these mixing angles at future colliders can test whether a minimal type I seesaw mechanism is the origin of the light neutrino masses, and it can be a first step towards probing leptogenesis as the mechanism of baryogenesis. We discuss how a stronger test could be achieved with an additional measurement of the heavy neutrino mass difference.…”

Searching for Charged Higgs Bosons via e + e − → H + H − → c ¯ b c ¯ b $$ \overline{c}b\overline{c}b $$ at Linear Colliders by Wei-Shu Hou, Rishabh Jain, Tanmoy Modak

“…In a general two Higgs doublet model without Z 2 symmetry, extra Yukawa couplings ρ tt and ρ tc can drive baryogenesis, but searches at the HL-LHC may still go empty-handed if the couplings are relatively weak. …”

First application of a liquid argon time projection chamber for the search for intranuclear neutron-antineutron transitions and annihilation in 40 Ar using the MicroBooNE detector by Abratenko, P, Alterkait, O, Andrade Aldana, D, Arellano, L, Asaadi, J, Ashkenazi, A, Balasubramanian, S, Baller, B, Barr, G, Barrow, D, Barrow, J, Basque, V, Benevides Rodrigues, O, Berkman, S, Bhanderi, A, Bhat, A, Bhattacharya, M, Bishai, M, Blake, A, Bogart, B, Bolton, T, Book, J, Camilleri, L, Cao, Y, Duffy, K, Green, P

“…A discovery of n⟶n̅ transition or a new best limit on the lifetime of this process would either constitute physics beyond the Standard Model or greatly constrain theories of baryogenesis, respectively. The approach presented in this paper makes use of deep learning methods to select n⟶n̅ events based on their unique features and differentiate them from cosmogenic backgrounds. …”

Significance of Broken μ−τ Symmetry in Correlating δCP, θ13, Lightest Neutrino Mass, and Neutrinoless Double Beta Decay 0νββ by Gayatri Ghosh

“…In this work, the idea is to link baryogenesis through leptogenesis and the hint of CP violation in the neutrino oscillation data to a breaking of the mu-tau symmetry. …”

A closer look in the mirror: reflections on the matter/dark matter coincidence by Arushi Bodas, Manuel A. Buen-Abad, Anson Hook, Raman Sundrum

“…The near cosmic coincidence is then explained by an approximate ℤ 2 exchange symmetry between the two sectors, where dark matter consists of stable dark neutrons, with matter and dark matter asymmetries arising via parallel WIMP baryogenesis mechanisms. Taking a top-down perspective, we point out that an adequate ℤ 2 symmetry necessitates solving the electroweak hierarchy problem in each sector, without our committing to a specific implementation. …”

Generating the observed baryon asymmetry from the inflaton field by Karouby, Johanna, Hertzberg, Mark Peter

“…We propose a mechanism by which the inflaton can generate baryogenesis, by taking the inflaton to be a complex scalar field with a weakly broken global symmetry, and present a new version of the Affleck–Dine mechanism. …”

Interplay among gravitational waves, dark matter and collider signals in the singlet scalar extended type-II seesaw model by Purusottam Ghosh, Tathagata Ghosh, Subhojit Roy

“…In short, we conclude from our analysis that the absence of new physics at the HL-LHC and/or various DM experiments in the near future will severely limit the prospects of detecting a stochastic GW at future GW experiments and will exclude the possibility of electroweak baryogenesis within this model.…”

A Survey of Schematic of Vacuum Quantum Structure: General Equation for EBSF (III) by Xiaodong Yang, Yuchen Yang, Zhen Luo, Yuanbo Bi

Distinct signatures of spinning PBH domination and evaporation: doubly peaked gravitational waves, dark relics and CMB complementarity by Nilanjandev Bhaumik, Anish Ghoshal, Rajeev Kumar Jain, Marek Lewicki

“…In our previous work, we studied the generation of a doubly peaked spectrum of induced stochastic gravitational wave background (ISGWB) for such a scenario and explored the possibility of probing a class of baryogenesis models wherein the emission of massive unstable particles from the PBH evaporation and their subsequent decay contributes to the matter-antimatter asymmetry. …”

First shot of the smoking gun: probing the electroweak phase transition in the 2HDM with novel searches for A → ZH in ℓ + ℓ − t t ¯ $$ {\ell}^{+}{\ell}^{-}t\overline{t} $$ and ννb... by Thomas Biekötter, Sven Heinemeyer, Jose Miguel No, Kateryna Radchenko, María Olalla Olea Romacho, Georg Weiglein

“…Remarkably, the ATLAS search in the ℓ + ℓ − t t ¯ $$ {\ell}^{+}{\ell}^{-}t\overline{t} $$ final state shows a local 2.85 σ excess (for masses of about 650 GeV and 450 GeV for the heavy and light resonance) in the 2HDM parameter region that would yield a FOEWPT in the early universe, which could constitute the first experimental hint of baryogenesis at the electroweak scale. We analyze the implications of this excess, and discuss the detectability prospects for the associated gravitational wave signal from the FOEWPT. …”
