Prompt heavy quarkonium production in association with a massive (anti)bottom quark at the LHC
In this work, we investigate the associated production of prompt heavy
quarkonium with a massive (anti)bottom quark to leading order in the NRQCD
factorization formalism at the LHC. We present numerical results for the
processes involving and . From our work,
we find that the production rates of these processes are quite large, and these
processes have the potential to be detected at the LHC. When is smaller
than about 10 GeV, the state give the main
contribution to the distribution of prompt with a (anti)bottom
quark production. For the process of , the
contribution of the CSM is larger than that in the COM at low region. We
also investigate the processes of and , in these processes, the distribution are dominated
by the CO Fock state contribution at the large region. These processes
provide an interesting signature that could be studied at the LHC, and the
measurement of these processes is useful to test the CSM and COM.Comment: 14 pages, 11 figures, accepted by Phys.Rev.
