  In the Color Glass Condensate formalism, charged hadron p_{T} distributions
in p+p collisions are studied by considering an energy-dependent broadening of
nucleon's density distribution. Then, in the Glasma flux tube picture, the
n-particle multiplicity distributions at different pseudo-rapidity ranges are
investigated. Both of the theoretical results show good agreement with the
recent experimental data from ALICE and CMS at \sqrt{s}=0.9, 2.36, 7 TeV. The
predictive results for p_{T} and multiplicity distributions in p+p and p+Pb
collisions at the Large Hadron Collider are also given in this paper.
