Logarithmic moments of B-meson quasidistribution amplitude

It was demonstrated that the lattice simulation of $B$-meson light-conedistribution amplitude (LCDA) is feasible via the quasi-distribution amplitude(quasi-DA) in large momentum effective theory (LaMET). The structures oflogarithmic moments (LMs) of $B$-meson quasi-DA is explored in this work. Theone-loop results indicate mixing in the matching: the $n$-th LM would be notonly factorized into the $n$-th LM of LCDA, but also other moments withdifferent power, accompanied by short distance coefficients. These resultssupply the understanding of the matching in LaMET and may provide guidance tothe lattice study of LMs or other parameters of $B$-meson LCDA.
