- W2103603869 abstract "In this work, we investigate the associated production of prompt heavy quarkonium and a massive (anti)bottom quark to leading order in the nonrelativistic QCD factorization formalism at the LHC. We present numerical results for the processes involving $J/ensuremath{psi}$, ${ensuremath{chi}}_{cJ}$, $ensuremath{Upsilon}$ and ${ensuremath{chi}}_{bJ}$. 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 ${p}_{T}$ is smaller than about 10 GeV, the $coverline{c}[^{1}S_{0}^{(8)}]$ states give the main contribution to the ${p}_{T}$ distribution of prompt $J/ensuremath{psi}$ with a massive (anti)bottom quark production. For the process $ppensuremath{rightarrow}ensuremath{Upsilon}+b(overline{b})$, the contribution of the color-singlet mechanism is larger than that in the color-octet mechanism at low ${p}_{T}$ region. We also investigate the processes $ppensuremath{rightarrow}{ensuremath{chi}}_{cJ}+b(overline{b})$ and $ppensuremath{rightarrow}{ensuremath{chi}}_{bJ}+b(overline{b})$; the ${p}_{T}$ distributions are dominated by the color-octet Fock-state contribution at large ${p}_{T}$. These processes provide an interesting signature that could be studied at the LHC, and the measurement of these processes is useful to test the color-singlet mechanism and color-octet mechanism." @default.
