| Publication Abstract: | We perform a study on the structure of inverse moment of quasi distributions, by taking $B$-meson quasi distribution amplitude (quasi-DA) as an example. Based on a one-loop calculation, we find that a naive perturbative matching relation for the first inverse moments of $B$-meson light-cone distribution amplitude (LCDA) and quasi-DA failed. Contrary to the naive expectation, to restore the factorization, the mixing with logarithmic moments must be included. We also derive the renormalization group equation and velocity evolution equation for the first inverse moment of quasi-DA. Our results can be useful either in understanding the patterns of perturbative matching in Large Momentum Effective Theory or evaluating inverse moment of $B$-meson LCDA on the lattice. |
