oral presentation Heavy Flavors and Quarkonia

Description

In this talk we present our results on production of heavy quarkonia pairs in the kinematics of future electron-proton colliders, like EIC, LHeC and FCC-he, and in ultraperipheral collisions at LHC. We analyzed in detail the mechanism which gives the dominant contribution in the leading order in strong coupling $\alpha_s$, both for the hidden-flavour quarkonia pairs and for the double heavy flavour $B_c$-mesons. For the hidden flavour quarkonia pairs, the suggested mechanism leads to production of quarkonia with opposite $C$-parity. The $B_c$-mesons are always produced as oppositely charged $B_c^+ B_c^-$ pairs. In all cases the quarkonia are produced predominantly with relatively small and oppositely directed transverse momenta. Using the Color Glass Condensate (CGC/Sat) approach, we estimated numerically the cross-section of this mechanism for different quarkonia states in the kinematics of existing and future photoproduction experiments.

This presentation is partially based on materials of our recent publication in Phys. Rev. D 105 (2022) 7, 076022 [arXiv:2202.03288].
