NLO QCD Corrections to $B_c$-to-Charmonium Form Factors

Abstract

The $B_c{(}^1{S}_0)$ meson to S-wave Charmonia transition form factors are calculated in next-to-leading order(NLO) accuracy of Quantum Chromodynamics(QCD). Our results indicate that the higher order corrections to these form factors are remarkable, and hence are important to the phenomenological study of the corresponding processes. For the convenience of comparison and use, the relevant expressions in asymptotic form at the limit of $m_c\to 0$ for the radiative corrections are presented.
