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 $e^{+}{e}^{-}$ Higgs factories such as FC…
