Cancellation of UV divergences in ghost-free infinite derivative gravity
Alexey S. Koshelev, Oleg Melichev, Leslaw Rachwal
We consider the most general covariant gravity action up to terms that are quadratic in curvature. These can be endowed with generic form factors, which are functions of the d'Alem…
Quadratic gravity with propagating torsion and asymptotic freedom
Oleg Melichev
We consider a class of metric-affine gravitational theories with action quadratic in curvature and torsion tensors. Using the heat kernel technique, we compute the torsion contribu…
On the renormalization of Metric-Affine Gravity theories
Oleg Melichev
We discuss the renormalization group in the context of gravitational theories with independent metric and affine connection. Considering a class of theories with both propagating t…
On the renormalization of Poincaré gauge theories
Oleg Melichev, Roberto Percacci
Poincaré Gauge Theories are a class of Metric-Affine Gravity theories with a metric-compatible (i.e. Lorentz) connection and with an action quadratic in curvature and torsion. We p…
