Production of the Doubly Heavy Baryons, $B_c$ Meson and the All-charm   Tetraquark at AFTER@LHC with Double Intrinsic Heavy Mechanism
  In the paper we discuss contribution of the doubly intrinsic heavy mechanism into the production of $B_c$ meson, the doubly heavy baryons and the all-charm tetraquark at a future fixed-target experiment at the LHC (AFTER@LHC). The production cross sections and the mean values of Feynman-x for the finale states are presented.
