Gravitational production of massive vectors non-minimally coupled to gravity
Bohdan Grzadkowski, Anna Socha
A quantum theory of massive Abelian vector bosons with non-minimal couplings to gravity has been studied within an evolving, isotropic, and homogeneous gravitational background. Th…
Measuring Inflaton Couplings via Primordial Gravitational Waves
Basabendu Barman, Anish Ghoshal, Bohdan Grzadkowski +1
We investigate the reach of future gravitational wave (GW) detectors in probing inflaton couplings with visible sector particles that can either be bosonic or fermionic in nature.…
Higgs boson induced reheating and ultraviolet frozen-in dark matter
Aqeel Ahmed, Bohdan Grzadkowski, Anna Socha
A reheating phase in the early universe is an essential part of all inflationary models during which not only the Standard Model (SM) quanta are produced but it can also shed light…
Implications of time-dependent inflaton decay on reheating and dark matter production
Aqeel Ahmed, Bohdan Grzadkowski, Anna Socha
We discuss the production of radiation and dark matter assuming a time-dependent inflaton decay rate during the reheating period. It is shown that the time dependence of the inflat…
Gravitational production of vector dark matter
Aqeel Ahmed, Bohdan Grzadkowski, Anna Socha
A model of vector dark matter that communicates with the Standard Model only through gravitational interactions has been investigated. It has been shown in detail how does the cano…
