Vector-tensor theories in metric-affine geometry
Tact Ikeda
We investigate ghost-free vector-tensor theories in metric-affine geometry. In all of our analysis, we start with the Lagrangian containing up to quadratic terms of first-order der…

Parametrized Love numbers of non-rotating black holes
Takuya Katagiri, Tact Ikeda, Vitor Cardoso
A set of tidal Love numbers quantifies tidal deformation of compact objects and is a detectable imprint in gravitational waves from inspiralling binary systems. The measurement of…

Consistency of higher derivative couplings to matter fields in scalar-tensor gravity
Tact Ikeda, Kazufumi Takahashi, Tsutomu Kobayashi
Recently, a generalization of invertible disformal transformations containing higher-order derivatives of a scalar field has been proposed in the context of scalar-tensor theories…
