Description
The kaon light-cone distribution amplitude (LCDA) is a crucial quantity in understanding the structure of hadrons. In this work, we use lattice quantum chromodynamics (LQCD), a powerful tool for calculating non-perturbative quantities. Since LQCD calculations are performed in Euclidean space, we apply the heavy-quark operator product expansion (HOPE) to connect light-cone parton dynamics with calculations in Euclidean space. This approach entails an OPE analysis of hadronic amplitudes in Euclidean space through the insertion of two local quark bilinears with a fictitious, valence heavy quark. We present the status of our numerical calculation for the first and second Mellin moments of the kaon LCDA obtained through the HOPE framework, advancing our understanding of parton distributions in mesons.
