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…
In search of a UV completion of the Standard Model - 378.000 models that don't work
Daniele Barducci, Marco Fabbrichesi, Carlos M. Nieto +2
Asymptotically safe extensions of the Standard Model have been searched for by adding vector-like fermions charged under the Standard Model gauge group and having Yukawa-like inter…
Safe and free instantons
Francesco Sannino, Vedran Skrinjar
We investigate the instanton dynamics of asymptotically safe and free quantum field theories featuring respectively controllable ultraviolet and infrared fixed points. We start by…
Nonminimal hints for asymptotic safety
Astrid Eichhorn, Stefan Lippoldt, Vedran Skrinjar
In the asymptotic-safety scenario for gravity, nonzero interactions are present in the ultraviolet. This property should also percolate into the matter sector. Symmetry- based argu…
Split Weyl transformations in quantum gravity
Carlos M. Nieto, Roberto Percacci, Vedran Skrinjar
We discuss various realizations of the Weyl group in the background field expansion of quantum gravity, in the presence of a cutoff, as required in applications of the functional r…
