Description
The measurement of the Higgs-charm Yukawa coupling is one
of the next milestones in Higgs physics at the LHC and serves as another
test of the consistency of the Standard Model. The Higgs-charm coupling
may be experimentally probed in different ways. These include for
example searches for signatures where a Higgs boson directly decays to a
pair of charm and anti-charm quarks or where a charm quark couples to
the Higgs boson in the initial state. This poster presents recent, novel CMS
results ([1][2][3]) which probe such signatures and place significant
constraints on |$\kappa_c$|.
