Quantum gravity contributions to the gauge and Yukawa couplings in proper time flow
Gabriele Giacometti, Kamila Kowalska, Daniele Rizzo +2
We derive quantum gravity contributions to the beta functions of the gauge and Yukawa couplings of a matter theory using the Schwinger proper-time flow equation. Working in the Ein…
On the universal content of the proper time flow in scalar and Yang-Mills theories
Gabriele Giacometti, Daniele Rizzo, Dario Zappala
We investigate the perturbative structure of the proper time renormalization group flow in scalar and Yang-Mills theories. Although the PT flow does not belong to the class of exac…
Gauge and parametrization dependence of Quantum Einstein Gravity within the Proper Time flow
Alfio Bonanno, Giovanni Oglialoro, Dario Zappalà
Proper time functional flow equations have garnered significant attention in recent years, as they are particularly suitable in analyzing non-perturbative contexts. By resorting to…
Spontaneous breaking of diffeomorphism invariance in conformally reduced quantum gravity
G. Giacometti, A. Bonanno, S. Plumari +1
We study the spontaneous breaking of diffeomorphism invariance using the proper-time non-perturbative flow equation in quantum gravity. In particular, we analyze the structure of t…
Higher-derivative four-dimensional sine-Gordon model
Matteo F. Bontorno, G. G. N. Angilella, Dario Zappala
The phase structure of a higher derivative sine-Gordon model in four dimensions is analysed. It is shown that the inclusion of a relevant two-derivative term in the action signific…
Perturbative and non-perturbative aspects of the proper time renormalization group
D. Zappala'
The renormalization group flow equation obtained by means of a proper time regulator is used to calculate the two loop beta function and anomalous dimension eta of the field for th…
