Abstract

In the paper, we make a comprehensive study of the hadroproduction of the B_c(B_c^*) meson via the gluon-gluon fusion mechanism at the RHIC and LHC colliders. Total and differential cross sections via the proton-nucleus (p\text\ensuremath-N) and nucleus-nucleus (N-N) collision modes have been discussed under various collision energies. To compare with those via the proton-proton collision mode at the LHC, we observe that a sizable number of B_c(B_c^*)-meson events can also be produced via the p\text\ensuremath-N and N-N collision modes at the RHIC and LHC. If assuming the spin-triplet B_c^* meson directly decays to the spin-singlet B_c meson with 100% probability, 1.2\ifmmode×\else\texttimes\fi10⁵ and 4.7\ifmmode×\else\texttimes\fi10⁵ B_c-meson events can be produced via the p\text\ensuremath-Au and Au-Au collision modes at the RHIC in one operation year, and 5.8\ifmmode×\else\texttimes\fi10⁶ and 4.6\ifmmode×\else\texttimes\fi10⁶ B_c-meson events can be produced via the p\text\ensuremath-Pb and Pb-Pb collision modes at the LHC in one operation year.
