Vector-Like Fermions at FCC-ee: NLO Higgs-Strahlung Signatures and Constraints
Carlo Marzo, Vinicius Padovani, Daniele Rizzo
We compute the one-loop effects of vector-like fermions (VLFs) on the Higgs-strahlung cross-section, the flagship precision observable of future Higgs factories such as FC…
Closed-form thermal threshold functions for the proper-time renormalisation group
Daniele Rizzo
We derive closed-form expressions for the thermal threshold functions of the finite-temperature proper-time renormalisation group (PTRG): until now these have been evaluated numeri…
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…
