Signals of the double intrinsic heavy quark at the current experiments

Abstract

In this paper we review existing data and analyze experimental opportunities for modern experiments to investigate the signals of intrinsic heavy quarks.

On the kinematic limit of the charm production in fixed-target experiments with the intrinsic charm from the target

“…Utilizing this idea, in Refs. [3,4] production of double charmed baryons and the J/ψ meson from the target was investigated at the STAR and LHCb/SMOG fixed-target programs [5,6]. By a straightforward calculation it was shown that in case of the production of intrinsic charm from the target, charm hadrons have a maximum momentum in the laboratory frame of only a few GeV/c and a rapidity y < 2.…”

Resolving the SELEX–LHCb double-charm baryon conflict: the impact of intrinsic heavy-quark hadroproduction and supersymmetric light-front holographic QCD

“…[27] and references therein). Both double J/ψ and doubly-charmed baryons could be produced perturbatively by mechanisms such as double parton scattering or some kind of ladder diagram where e.g.…”

Resolving the SELEX--LHCb Double-Charm Baryon Conflict: The Impact of Intrinsic Heavy-Quark Hadroproduction and Supersymmetric Light-Front Holographic QCD

“…Note that gluon-gluon fusion, quark-antiquark annihilation and the gluon splitting mechanism of perturbative QCD can explain neither the NA3 cross section nor the x F distribution (see Ref. [27] and references therein). Both double J/ψ and doubly-charmed baryons could be produced perturbatively by mechanisms such as double parton scattering or some kind of ladder diagram where e.g.…”
