Are the angular correlations in pA collisions due to a Glasmion or Bose condensation?
چکیده انگلیسی

Experiments at the LHC have recently reported results on the angular asymmetry coefficients vn[m]vn[m], for various angular moments n and orders of cumulants m  , in high multiplicity p+Pbp+Pb collisions. These coefficients are large, and have both even and odd moments. We discuss here some of the implications of these results for our understanding of the initial state of the collision (Color Glass Condensate) and for the evolution in the final state (Glasma and thermalized Quark Gluon Plasma). We show the Color Glass Condensate predicts large even moments, vnvn with n   an even integer. Odd moments are generated by final state interactions or fragmentation. For a multi-particle determination of v2[m]v2[m], where m is the number of particles used to determine the correlation, we argue that if these coefficients approach equality for large m in high multiplicity events, this may imply the existence of either solitonic solutions or Bose condensation either for the JIMWLK action that describes the CGC, or for the Glasma that might be produced in such a collision.
