, 2020 The article communicates exploration of gravitational baryogenesis in presence of $$f(Q,{\mathcal { T}})$$ gravity where Q denote the nonmetricity and $${\mathcal { T}}$$ the trace of the energy momentum tensor. We study various baryogenesis interactions

Long‐Baseline Oscillation Experiments as a Tool to Probe High Energy Flavor Symmetry Models
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We review the current status of neutrino oscillation experiments, mainly focusing on T2(H)K, NOνA, and DUNE. Their capability to probe high energy physics is found in the precision measurement of the CP phase and θ23. In general, neutrino mass models predict correlations among the mixing angles that can be used to scan and shrink their parameter space.

Hidden sector baryogenesis [PDF]
Physics Letters B, 2006 We introduce a novel mechanism for baryogenesis, in which mixed anomalies between the hidden sector and $U(1)_{baryon}$ drive the baryon asymmetry. We demonstrate that this mechanism occurs quite naturally in intersecting-brane constructions of the Standard Model, and show that it solves some of the theoretical difficulties faced in matching ...

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.Searches are being carried out at the Large Hadron Collider (LHC) for the decay of the CP‐odd scalar (A0) in two‐Higgs‐doublet models (2HDMs) with natural flavour conservation (NFC) in the channel A0⟶h0Z, where h0 is either the discovered 125 GeV Higgs boson or is an undiscovered CP‐even scalar with a mass below 125 GeV.

Electroweak Phase Transitions in Einstein’s Static Universe
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We suggest using Einstein’s static universe metric for the metastable state after reheating, instead of the Friedman‐Robertson‐Walker spacetime. In this case, strong static gravitational potential leads to the effective reduction of the Higgs vacuum expectation value, which is found to be compatible with the Standard Model first‐order electroweak phase

Supersymmetric electroweak baryogenesis [PDF]
Journal of High Energy Physics, 2000 We re-examine the generation of the baryon asymmetry in the minimal supersymmetric standard model (MSSM) during the electroweak phase transition. We find that the dominant source for baryogenesis arises from the chargino sector. The CP-violation comes from the complex phase in the mu parameter, which provides CP-odd contributions to the particle ...

Complementary Probes of the Dimension‐6 Operator via Gravitational Waves and Multi‐Higgs Production
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.We investigate the phenomenological consequences of a dimension‐6 operator H†H3/Λ2, Λ is the effective scale at which new physics takes over, which modifies the scalar potential of the standard model and can induce a strong first‐order electroweak phase transition (SFOEWPT). We estimate the lower limit on the effective scale Λ to be 515 GeV from the di‐

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 Neutrino physics is a mature branch of science with all the three neutrino mixing angles and two mass squared differences determined with high precision. In spite of several experimental verifications of neutrino oscillations and precise measurements of two mass squared differences and the three mixing angles, the unitarity of the leptonic mixing ...

GalaxiesWe propose that modifications to the Higgs potential within a narrow atmospheric layer near the event horizon of an astrophysical black hole could significantly enhance the rate of sphaleron transitions, as well as transform the Chern–Simons number into ...

The serendipity of electroweak baryogenesis [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 The origin of the matter–antimatter asymmetry of the universe remains unexplained in the Standard Model (SM) of particle physics. The origin of the flavour structure is another major puzzle of the theory. In this article, we report on recent work attempting to link the two themes through the appealing framework of electroweak (EW) baryogenesis. We show
