New Gauge Forces, Neutron Stars and Schwinger Neutrino Production
Yuxin Liu, Zhen Liu, Andrey Shkerin +2
We investigate neutrino effects of new long-range forces arising from gauging , or symmetries of the Standard Model. The leptonic potential generated b…
Holographic phase transitions via thermally-assisted tunneling
Tony Gherghetta, Arpon Paul, Andrey Shkerin
We construct the thermal bounce solution in holographic models that describes first-order phase transitions between the deconfined and confined phases in strongly-coupled gauge the…
Probing the Local Dark Matter Halo with Neutrino Oscillations
Tony Gherghetta, Andrey Shkerin
Dark matter particles can form halos gravitationally bound to massive astrophysical objects. The Earth could have such a halo where depending on the particle mass, the halo either…
Gravitational Portals with Non-Minimal Couplings
Simon Clery, Yann Mambrini, Keith A. Olive +2
We consider the effects of non-minimal couplings to curvature of the form , for three types of scalars: the Higgs boson, the inflaton, and a scalar dark matter candidate…
Preheating in Palatini Higgs inflation on the lattice
Frédéric Dux, Adrien Florio, Juraj Klarić +2
We study preheating following Higgs inflation in the Palatini formulation of gravity. We numerically evolve perturbations of the radial mode of the Higgs field and that of three sc…
Einstein-Cartan Portal to Dark Matter
Mikhail Shaposhnikov, Andrey Shkerin, Inar Timiryasov +1
It is well-known since the works of Utiyama and Kibble that the gravitational force can be obtained by gauging the Poincaré group, which puts gravity on the same footing as the Sta…
