Description
We discuss the decays of the Higgs boson to an $S$-wave vector quarkonium plus
a photon. The decay rate is sensitive to both the size and the phase
information of the Higgs-charm coupling through quantum interference.
We improve the theoretical predictions by resumming logarithms to
next-to-leading log accuracy and by calculating relativistic corrections of
order $v^2$, where $v$ is the heavy-quark velocity in the quarkonium rest frame.
These refinements reduce the theoretical uncertainties in the decay rate and
open the door to improved determinations at the LHC of the Higgs-boson Yukawa
couplings to charm and bottom quarks.
