Description
A generic expression to compute triple parton scattering (TPS) cross sections in high-energy proton-proton (p-p) and proton-nucleus (p-A) collisions will be presented as a function of the corresponding single-parton-scattering (SPS) cross sections and the transverse parton distribution in the proton encoded in the σeff,TPS effective parameter. The value of σeff,TPS is found to be closely related to the effective cross section that characterizes double-parton scatterings (DPS). Estimates for triple charm (ccbar) and bottom (bbbar) production (including quarkonia bound states) in pp and p-A collisions at LHC, FCC, and ultrahigh cosmic-ray energies will be presented based on next-to-next-to-leading order perturbative calculations for the corresponding SPS cross sections.
