Black Holes and Baryon Number Violation: Unveiling the Origins of Early Galaxies and the Low-Mass Gap
Merab Gogberashvili, Alexander S. Sakharov
We 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…
Looking at the NANOGrav Signal Through the Anthropic Window of Axion-Like Particles
Alexander S. Sakharov, Yury N. Eroshenko, Sergey G. Rubin
We explore the inflationary dynamics leading to formation of closed domain walls in course of evolution of an axion like particle (ALP) field whose Peccei-Quinn-like phase transiti…
The Higgs field and early universe cosmology: a (brief) review
Bart Horn
We review and discuss recent work exploring the implications of the Higgs field for early universe cosmology, and vice versa. Depending on the model under consideration the Higgs m…
Effective-energy universality approach describing total multiplicity centrality dependence in heavy-ion collisions
Edward K. Sarkisyan-Grinbaum, Aditya Nath Mishra, Raghunath Sahoo +1
The recently proposed participant dissipating effective-energy approach is applied to describe the dependence on centrality of the multiplicity of charged particles measured in hea…
Centrality dependence of midrapidity density from GeV to TeV heavy-ion collisions in the effective-energy universality picture of hadroproduction
Edward K. G. Sarkisyan, Aditya Nath Mishra, Raghunath Sahoo +1
The dependence on centrality, or on the number of nucleon participants, of the midrapidity density of charged particles measured in heavy-ion collisions at the collision energy of…
Size of Shell Universe in Light of Fermi GBM Transient Associated with GW150914
Merab Gogberashvili, Alexander Sakharov, Edward Sarkisyan-Grinbaum
The possible gamma ray burst occurred in location and temporal consistence with gravitational wave event GW150914, as reported by Fermi Gamma-ray Burst Monitor (GBM), offers a new…
