Abstract：
In the Color Glass Condensate formalism, charged hadron p_T spectra in p+p and p+Pb collisions are studied by considering an energy-dependent broadening of nucleon density distribution. Then, in the glasma flux tube picture, the n-particle multiplicity distributions at different pseudo-rapidity ranges are investigated. Both the theoretical results show good agreement with the recent experimental data from ALICE and CMS at LHC energies. The predictive results for p_T or multiplicity distributions in p+p and p+Pb collisions at the Large Hadron Collider are also given in this paper.
