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…

Metric-Affine Gravity as an Effective Field Theory

A. Baldazzi, O. Melichev, R. Percacci

We discuss theories of gravity with independent metric (or frame field) and connection, from the point of view of effective field theory. We count the parity-even Lagrangian terms…

Can quantum fluctuations differentiate between standard and unimodular gravity?

Gustavo P. de Brito, Oleg Melichev, Roberto Percacci +1

We formally prove the existence of a quantization procedure that makes the path integral of a general diffeomorphism-invariant theory of gravity, with fixed total spacetime volume,…
