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.…

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…
