[Theory-seminars] Theory Seminar Monday - Robert Perry

[Colin Egerer]

Hello All,

This coming Monday, November 15th at 9:00AM (EST), Robert Perry will give a seminar on https://jlab.bluejeans.com/319089525/6769<https://urldefense.proofpoint.com/v2/url?u=https-3A__jlab.bluejeans.com_319089525_6769&d=DwMFAw&c=CJqEzB1piLOyyvZjb8YUQw&r=AIMSQQ81YDyrZuJNGks2qw&m=x29E57UMx34WjoS-yLXZS2qNLfa_SlSw0J1QuFd6u80&s=YZDnEovFtz29HvbN26a0A0rgHtJ1M_tEUQ7YAbyNdgA&e=>.

Theory Seminar
Monday November 15th, 9:00AM

Robert Perry (National Yang Ming Chiao Tung University) will speak about "Lattice QCD calculation of Mellin moments for the pion distribution amplitude using the HOPE Method"

Abstract:
The pion light-cone distribution amplitude (LCDA) is a key object of interest for high-energy exclusive processes in quantum chromodynamics. In this talk, I will discuss the calculation of the second Mellin moment of the pion LCDA using the heavy-quark operator product expansion (HOPE) method. The resulting value for the second Mellin moment is compatible with those from previous determinations of this quantity. The HOPE method can also be applied to extract higher moments of the LCDA, and in this talk I also describe the early progress towards calculating the fourth Mellin moment using the same approach.


Have a pleasant weekend!
Astrid, Colin & Patrick
