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.
pp→hc。作为初步估计，我们发现，在大型强子对撞机（LHC）上，当积分亮度达到3000 fb⁻¹时，相对于魅夸克汤川耦合的标准模型（SM）值，应该有可能得出量级为一的约束。作为该分析的一个副产品，我们给出了pp→hD⁽*⁾弱电过程的单举截面的估计。在标准模型内，即使在高亮度阶段，LHC也无法探测到后者。
