Abstract
The Compact Muon Solenoid Experiment measured dijets produced in photon-nuclear collisions using data taken at the Large Hadron Collider in late 2015. Dijet measurements are potentially useful in constraining the gluon density over a wide range of x and Q, which is needed in order to measure the quark-gluon plasma viscosity and to search for the color-glass condensate. Recently it has been suggested by several theoretical groups that photon induced dijets can also be used to examine the correlation between the gluons in the nucleus. This analysis focused on the latter, examining azimuthal correlations between the total transverse momentum of the dijets and the momentum difference of the dijets. Following the prescription suggested by theorists, a positive correlation was found.
