报告摘要：

The CGC framework provides the description of dense parton density and predicts the gluon saturation phenomenon at small-x. In recent works, we have incorporated Sudakov resummation into the CGC framework to calculate the qT distribution of Z0-boson and the dijet/dihadron azimuthal angular correlation in forward pp and pA collisions.

CMS collaboration has reported large values of elliptic flow (v2) for J/ψ mesons and for D0 mesons in high multiplicity pA collisions, which hydrodynamics approach fails to reproduce. Recently, we have described the v2 of light hadrons, heavy quarkonia and open heavy mesons utilizing the CGC formalism. This indicates the large v2 in small collisional systems arises from the initial state effect and therefore cannot be interpreted as a signal of the appearance of QGP matter in pA collisions.
