Next-to-next-to-leading-order radiative corrections to e+e − → χ cJ + γ at B factory
Abstract Within the nonrelativistic QCD (NRQCD) factorization framework, we have computed the O α s 2 $$ \mathcal{O}\left({\alpha}_s^2\right) $$ corrections to the exclusive production of P-wave spin-triplet charmonia χ cJ (J = 0, 1, 2) accompanied with a hard photon at B factory. For the first time...
