Baryogenesis from symmetry principle
Physics Letters B, 2016 In this work, a formalism based on symmetry which allows one to express asymmetries of all the particles in terms of conserved charges is developed. The manifestation of symmetry allows one to easily determine the viability of a baryogenesis scenario and

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 The future long baseline experiments such as DUNE and T2HKK have promising prospects to determine the neutrino mass hierarchy and measuring standard CP phase δ. However, presence of possible nonstandard interactions of neutrinos with matter may intricate this picture and is the subject matter of the present work.

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.

Gravitational baryogenesis in DGP brane cosmology
European Physical Journal C: Particles and Fields, 2018 We consider the imbalance of matter and antimatter by using a gravitational baryogenesis mechanism in the background of Dvali–Gabadadze–Porrati (DGP) brane cosmology.

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

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 ...

Phase transitions and baryogenesis from decays
Journal of High Energy Physics, 2017 We study scenarios in which the baryon asymmetry is generated from the decay of a particle whose mass originates from the spontaneous breakdown of a symmetry.

Ultra-relativistic bubbles from the simplest Higgs portal and their cosmological consequences
Journal of High Energy Physics, 2022 We analyze phase transitions in the minimal extension of the SM with a real singlet scalar field. The novelty of our study is that we identify and analyze in detail the region of parameter space where the first order phase transition can occur and in ...

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 ...

The Discreet Charm of Higgsino Dark Matter: A Pocket Review
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low‐scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational ...
