Dear all,
Our next seminar will be Tuesday, April 14th, in Science Building III, Room SC427, from 14:20 to
15:20.
Speaker: 張聖彬 (Alex Chang)
Title: Parton physics from a heavy-quark operator product
expansion: Dynamical lattice QCD calculation of moments of the pion and
kaon light-cone distribution amplitudes
Abstract:
The
light-cone distribution amplitude (LCDA) is a fundamental
non-perturbative quantity for understanding hadron structure and
exclusive scattering processes. We report on our calculation of the pion
and kaon LCDAs using the heavy-quark operator product expansion (HOPE)
framework. This method employs an OPE analysis of hadronic amplitudes
through the inclusion of a fictitious valence heavy quark. In these
talk, we report progress on the determination of the first three
nontrivial Mellin moments of the kaon LCDAs from dynamical lattice QCD
calculations, and we summarize the recently published continuum-limit
result for the pion fourth Mellin moment obtained in the quenched
approximation, thereby demonstrating the feasibility of the HOPE method
for accessing higher moments.
See you all there.
Best,
Wayne
