HYM-flation: Yang–Mills cosmology with Horndeski coupling
We propose new mechanism for inflation using classical SU(2) Yang–Mills (YM) homogeneous and isotropic field non-minimally coupled to gravity via Horndeski prescription. This is the unique generally and gauge covariant ghost-free YM theory with the curvature-dependent action leading to second-order...
