Infrared divergences of $B$ meson exclusive decays to P-wave charmonia in QCD factorization and nonrelativistic QCD

Zhong-Zhi Song, Ce Meng, Ying-Jia Gao +1

In the framework of QCD factorization, we study the $B$ meson exclusive decays $B\to {\chi }_{cJ}K$ where the spin-triplet P-wave charmonium states ${\chi }_{cJ}(J=0,1,2)$ are described by the…
