Suppression of matter couplings with a vector field in generalized Proca theories
Shintaro Nakamura, Ryotaro Kase, Shinji Tsujikawa
We derive the profile of a vector field coupled to matter on a static and spherically symmetric background in the context of generalized Proca theories. The cubic Galileon self-int…
Black holes in vector-tensor theories
Lavinia Heisenberg, Ryotaro Kase, Masato Minamitsuji +1
We study static and spherically symmetric black hole (BH) solutions in second-order generalized Proca theories with nonminimal vector field derivative couplings to the Ricci scalar…
Hairy black-hole solutions in generalized Proca theories
Lavinia Heisenberg, Ryotaro Kase, Masato Minamitsuji +1
We present a family of exact black-hole solutions on a static spherically symmetric background in second-order generalized Proca theories with derivative vector-field interactions…
Cosmology in generalized Proca theories
Antonio De Felice, Lavinia Heisenberg, Ryotaro Kase +3
We consider a massive vector field with derivative interactions that propagates only the 3 desired polarizations (besides two tensor polarizations from gravity) with second-order e…
Matter perturbations in Galileon cosmology
Antonio De Felice, Ryotaro Kase, Shinji Tsujikawa
We study the evolution of matter density perturbations in Galileon cosmology where the late-time cosmic acceleration can be realized by a field kinetic energy. We obtain full pertu…
