Comments on Multiplicity in Proton Nucleus Collisions
We model particle creation in the central rapidity region in ultra-relativistic nuclear collisions by assuming an intermediate state of color flux. Our starting point is that nucleon-nucleon collisions are dominated by single gluon exchange.1 This causes the color to flip from singlet to octet so that the two receding nucleons become linked by a flux tube with the diameter of the nucleon. This flux tube then materializes to produce the observed phenomena. In the case of a proton-nucleus collision there will be several gluon exchanges for each quark in the projectile, which will change the details of the flux tube’s formation and materialization. In what follows, we make some comments on this problem.
