Exploring the meson light-cone distribution amplitudes from lattice QCD

by Prof. 其安 张



Weak decays of heavy mesons provide an excellent laboratory to test the Standard Model and search for new physics. Theoretical predictions for heavy meson decays based on QCD factorization theorems hinge critically on the knowledge of the light-cone distribution amplitudes (LCDAs) of both heavy and light mesons. In this talk, I will present a succinct overview of our recent works on lattice QCD calculations for light and heavy meson light-cone distribution amplitudes within the framework of large-momentum effective theory. These results will provide first-principle predictions of critical nonperturbative inputs for both experimental and theoretical research.
