Production of the Doubly Heavy Baryons, $B_c$ Meson and the All-charm Tetraquark at AFTER@LHC with Double Intrinsic Heavy Mechanism

Abstract

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.

Bound state formation in the DDK system

“…In this line, experimental and theoretical efforts, during the past years, have been dedicated to the study of doubly charmed baryons, like Ξ þ cc , Ξ þþ cc , Ω þ cc (see, for example, Refs. [3][4][5][6][7][8][9][10][11][12][13][14][15][16]), and doubly charmed mesons, like the T cc family and others (see, for example, Refs. [17][18][19][20][21][22][23][24][25][26][27]).…”

“…The production of the double-charm baryons at AFTER@LHC with the intrinsic charm is investigated in Ref. [34].…”

“…These observations indicate the importance of the high x F domain and fixed-target LHC experiments such as SMOG@LHCb [46,47] and AFTER@LHC [48,49] for observing the hadroproduction of exotic heavy quark states. As explained above, one also can understand why the radiative transition 3621|(cc)q → 3520|[qc]c + γ is strongly suppressed due to the very small overlap of their respective radial wavefunctions.…”
