Description
Higgs exclusive decay to a J/Psi plus a photon is a clean channel to probe the Higgs-charm coupling. In this process, large logarithms log(m_c/m_H) are resummed using the evolution of the lightcone distribution amplitude (LCDA), which in turn is matched to the long-distance matrix elements in NRQCD at the scale m_c. We will demonstrate the matching to O(v^4) and its phenomenological implications.
