Query: $B_c$ Meson at LHC   In the framework of perturbative QCD and potential models of heavy
quarkonium, total cross-sections and differential characteristics of hadronic
production for different spin states of the $B_c$-meson family are calculated
at energies of LHC. Theoretical predictions for masses and branching ratios of
$B_c$ decays are given, which allows one to make estimates for an expected
number of reconstructed events with $B_c$.
