Brivio I, Goertz F, Isidori G. Probing the Charm Quark Yukawa Coupling in Higgs+Charm Production. Phys Rev Lett. 2015;115(21):211801.
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?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?hD^{(*)} electroweak cross section. Within the SM, the latter turns out to be not accessible at the LHC even in the high-luminosity phase.
