A factorization theorem connecting the light-cone distribution amplitudes of heavy-flavor mesons in QCD and HQET
Saadi Ishaq, Yu Jia, Xiaonu Xiong +1
The light-cone distribution amplitude (LCDA) of a heavy-light meson defined in heavy quark effective theory (HQET), is a fundamental nonperturbative input to account for innumerabl…

Exclusive decay to double at next-to-leading order in
Bin Gong, Yu Jia, Jian-Xiong Wang
Within the nonrelativistic QCD (NRQCD) factorization framework, we calculate the exclusive decay process η_b \to J/ψJ/ψto next-to-leading order in the strong coupling constant, whi…
