CGC/saturation approach for high energy soft interactions: $\mathbf{v_2}$ in proton-proton collisions

Abstract

In this paper we continue our program to construct a model for high energy soft interactions, based on the CGC/saturation approach. We demonstrate that in our model which describes diffractive physics as well as multi-particle production at high energy, the density variation mechanism leads to the value of v2v_2 which is about 60%÷70%60\% \div 70\% of the measured v2v_2. Bearing in mind that in CGC/saturation approach there are two other mechanisms present: Bose enhancement in the wave function and local anisotropy, we believe that the azimuthal long range rapidity correlations in proton-proton collisions stem from the CGC/saturation physics, and not from quark-gluon plasma production.
