Resonant Gravitational Production of Chiral Dark Photons
Leah Jenks, Marc Kamionkowski, Edward W. Kolb
Vector fields with a chiral, parity-odd coupling to a pseudoscalar field are known to undergo resonant amplification. In this work, we study this phenomenon in the context of cosmo…
Cosmological gravitational particle production in multifield inflation
Edward W. Kolb, Sarunas Verner, Jingyuan Wang
We study cosmological gravitational particle production (CGPP) of dark matter in two-field inflationary backgrounds with both flat and curved field-space geometries. As a concrete…
Nonthermal leptogenesis via cosmological gravitational particle production is tested by inflationary gravitational waves
Tammi Chowdhury, Leah Jenks, Edward W. Kolb +2
We explore the coincidence of scales between cosmic inflation and right-handed neutrinos in seesaw models. We show that inflation models, which will be tested by next-generation CM…
