Non-linearly ghost-free higher curvature gravity
Katsuki Aoki
We find unitary and local theories of higher curvature gravity in the vielbein formalism, known as the Poincaré gauge theory by utilizing the equivalence to the ghost-free massive…

Gravitational positivity bounds
Junsei Tokuda, Katsuki Aoki, Shin'ichi Hirano
We study the validity of positivity bounds in the presence of a massless graviton, assuming the Regge behavior of the amplitude. Under this assumption, the problematic -channel…

Consistent inflationary cosmology from quadratic gravity with dynamical torsion
Katsuki Aoki, Shinji Mukohyama
The idea of gauge theories of gravity predicts that there should exist not only the massless graviton but also massive particles carrying the gravitational force. We study the cosm…
