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…

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…
