Abstract：

Heavy flavor physics, in particular B physics, is one of the frontiers in particle physics research. The factorization theorem is usually used to study the B meson weak decays, which can separate the perturbatively calculable hard kernel and nonperturbative quantities. These nonperturbative quantities, such as light-cone distribution amplitude (LCDAs), describe the internal structure and properties of particles and are key inputs for both theoretical and experimental analysis. I will introduce our recent studies on the B-meson LCDAs in terms of large momentum effective theory, heavy quark effective theory and lattice QCD.
