Next-to-leading order QCD corrections to ${\chi }_{cJ}{W}^{+}b$ associated production from top-quark decay

Abstract

We calculate the next-to-leading order QCD corrections to the excited charmonium ${\chi }_{cJ}$ associated with $W^{+}b$ production from top-quark decay. Our results show that detecting the ${\chi }_{c0}$ production from top-quark decay is very difficult, but the ${\chi }_{c1}$ and ${\chi }_{c2}$ productions have the potential to be detected at the LHC. If the prompt ${\chi }_{cJ}$ production from top-quark decay is really detected at the LHC, it will be useful not only for investigating $J/\psi$ production from top-quark decay but also for understanding the heavy quarkonium production mechanism.
