Quark correlations in the Color Glass Condensate Academic Article uri icon


  • The ridge correlation observed at the Large Hadron Collider (LHC), first in high-multiplicity pp collisions [1], then in p-Pb collisions [2] and, more recently [3], in pp events with multiplicities close to those in minimum bias collisions, has been in the center of interest of the heavy-ion community for several years. Two main lines of explanations are discussed at present. One is based on a collective hydrodynamic behavior of the system produced in the collision in an analogous manner as in heavy-ion collisions. The other one is based on the Color Glass Condensate (CGC) framework to describe high-energy Quantum Chromodynamics in a weak coupling but nonperturbative regime, where a quantitative description of the data is achieved [4] in the “glasma graph” approach which ascribes the origin of the correlations entirely to the structure of the initial state. Though it is likely that …
