TL;DR: In this paper, high multiplicity events in p+p collisions are studied using the theory of the color glass condensate, and it is shown that intrinsic fluctuations of the proton saturation momentum scale are needed in addition to the sub-nucleonic color charge fluctuations to explain the very large multiplicity tail of distributions in p +p collisions.

TL;DR: In this paper, a semi-holographic model for the out-of-equilibrium dynamics during the partonic stages of an ultrarelativistic heavy-ion collision was developed.
Abstract: We develop a semi-holographic model for the out-of-equilibrium dynamics during the partonic stages of an ultrarelativistic heavy-ion collision. The model combines a weakly-coupled hard sector, involving gluon modes with energy and momenta of the order of the saturation momentum and relatively large occupation numbers, with a strongly-coupled soft sector, which physically represents the soft gluons radiated by the hard partons. The hard sector is described by perturbative QCD, more precisely, by its semi-classical approximation (the classical Yang-Mills equations) which becomes appropriate when the occupation numbers are large. The soft sector is described by a marginally deformed conformal field theory, which in turn admits a holographic description in terms of classical Einstein’s equations in AdS 5 with a minimally coupled massless ‘dilaton’. The model involve two free parameters which characterize the gauge-invariant couplings between the hard and soft sectors. Via these couplings, the hard modes provide dynamical sources for the gravitational equations at the boundary of AdS 5 and feel the feedback of the latter as additional soft sources in the classical Yang-Mills equations. Importantly, the initial conditions for this coupled dynamics are fully determined by the hard sector alone, i.e. by perturbative QCD, and are conveniently given by the color glass condensate (CGC) effective theory. We also develop a new semi-holographic picture of jets in the QGP by attaching a non-Abelian charge to the endpoint of the trailing string in AdS 5 representing a heavy quark. This leads to modified Nambu-Goto equations for the string which govern the (collisional and radiative) energy loss by the heavy quark towards both hard and soft modes.

TL;DR: In this paper, the double differential cross-sections of prompt and non-prompt meson production were measured as a function of the J/ψ transverse momentum and rapidity in the nucleon-nucleon center-of-mass frame.

Journal ArticleDOI
TL;DR: In this article, the authors considered the target nucleus as a color glass condensate and the projectile deuteron as a dilute system of valence quarks and obtained good agreement with the BRAHMS minimum bias data on charged hadron production in the forward rapidity (y = 3.2 ) and low p t region.
