Mapping color fluctuations in the photon in ultraperipheral heavy ion collisions at the Large Hadron Collider

Mapping color fluctuations in the photon in ultraperipheral heavy ion collisions at the Large Hadron Collider

We model effects of color fluctuations (CFs) in the light-cone photon wave function and for the first time make predictions for the distribution over the number of wounded nucleons ν in the inelastic photon–nucleus scattering. We show that CFs lead to a dramatic enhancement of this distribution at ν...
