Are the Angular Correlations in pA Collisions due to a Glasmion or Bose Condensation ?

Understand

Experiments at the LHC have recently reported results on the angular asymmetry coefficients $v_n[m]$, for various angular moments $n$ and orders of cumulants $m$, in high multiplicity p+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, $v_n$ with $n$ an even integer.
