First lattice QCD calculation of $J/\ddot{I}ˆ$ semileptonic decay containing $D$ and $D_s$ particles

Yu Meng, Jin-Long Dang, Chuan Liu +4

We perform the first lattice calculation on the semileptonic decay of $J/\ddot{I}ˆ$ using the (2+1)-flavor Wilson-clover gauge ensembles generated by CLQCD collaboration. Three gauge ense…
