Description

The pion light-cone distribution amplitude (LCDA) is an essential non-perturbative input for a range of high-energy exclusive processes in quantum chromodynamics. Building upon previous work, I will describe the calculation of the fourth Mellin moment of the pion LCDA in the continuum using the heavy-quark operator product expansion (HOPE) method.
