Abstract:
The light cone distribution amplitudes (LCDAs) give the internal structures of light mesons, are critical inputs for the description of hard exclusive reactions. The large-momentum effective theory (LaMET) allows to access the entire x-dependence of the DAs from first principle lattice calculations. In this talk, I will discuss how to calculate LCDAs under the LaMET, including how to handle the divergence structure of the quasi-light-front (quasi-LF) correlation and how to match the quasi-DAs to LCDAs. Then, I will show the recently calculated Pion and Kaon LCDAs.
