On Lorentz-invariant bi-spin-2 theories
Rampei Kimura, Atsushi Naruko, Daisuke Yamauchi
We investigate a Lorentz invariant action which is quadratic in two rank-2 symmetric tensor fields in Minkowski spacetime. We apply a scalar-vector-tensor decomposition to two tens…
UV sensitive one-loop matter power spectrum in degenerate higher-order scalar-tensor theories
Shin'ichi Hirano, Tsutomu Kobayashi, Daisuke Yamauchi +1
We study matter density perturbations up to third order and the one-loop matter power spectrum in degenerate higher-order scalar-tensor (DHOST) theories beyond Horndeski. We system…
Testing gravity theories with cosmic microwave background in the degenerate higher-order scalar-tensor theory
Takashi Hiramatsu, Daisuke Yamauchi
We study the cosmic microwave background (CMB) in the framework of the degenerate higher-order scalar-tensor (DHOST) theory to test gravity theories. This theoretical framework inc…
