Perturbative limits on axion-SU(2) gauge dynamics during inflation from the energy density of spin-2 particles
Koji Ishiwata, Eiichiro Komatsu
We investigate the conditions under which the perturbative treatment of the backreaction of spin-2 particles on the dynamics of an axion-SU(2) gauge field system breaks down during…

Schwinger Effect by an Gauge Field during Inflation
Kaloian D. Lozanov, Azadeh Maleknejad, Eiichiro Komatsu
Non-Abelian gauge fields may exist during inflation. We study the Schwinger effect by an gauge field coupled to a charged scalar doublet in a (quasi) de Sitter background a…
