Probing the Charm Quark Yukawa Coupling in Higgs + Charm Production


Brivio, Ilaria; Goertz, Florian; Isidori, Gino (2015). Probing the Charm Quark Yukawa Coupling in Higgs + Charm Production. Physical Review Letters, 115(21):211801.

Abstract

We propose a new method for determining the coupling of the Higgs boson to charm quarks, via Higgs production in association with a charm-tagged jet: $pp \to hc$. As a first estimate, we find that at the LHC with $3000 fb^{-1}$, it should be possible to derive a constraint of order one, relative to the standard model (SM) value of the charm Yukawa coupling. As a by-product of this analysis, we present an estimate of the exclusive $pp \to hD^{(*)}$ electroweak cross section. Within the SM, the latter turns out to be not accessible at the LHC even in the high-luminosity phase.
