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…
Quantum fields without Wick rotation
Alessio Baldazzi, Roberto Percacci, Vedran Skrinjar
We discuss the calculation of one-loop effective actions in Lorentzian spacetimes, based on a very simple application of the method of steepest descent to the integral over the fie…
Wicked metrics
Alessio Baldazzi, Roberto Percacci, Vedran Skrinjar
There are various ways of defining the Wick rotation in a gravitational context. There are good arguments to view it as an analytic continuation of the metric, instead of the coord…
