Abstract: Bose-Einstein correlation between identical particles predicts the enhancement in the number of pairs of gluons with the same quantum numbers and small relative momentum. In this talk, I will show that these preexisting correlations in a hadronic wave function can be probed in Deep Inelastic Scattering experiments at high energy. Specifically, I will consider the diffractive dijet + gluon jet production. Working in the two gluon exchange approximation, we found the azimuthal dependence displays a peak at the zero relative angle between the transverse momentum imbalance of the quark-antiquark dijet and the transverse momentum of the gluon jet. Our calculations explicitly show that the peak originates from Bose correlation of the wave function. I will also discuss our ongoing effort to go beyond the two gluon exchange approximation and evaluate the effects of gluon saturation.
