  We present various predictions for the upcoming p+Pb collisions at \sqrt{S}=5
TeV within the color glass condensate (CGC) formalism, including single
inclusive charged hadron production, single inclusive prompt photon production,
direct photon production, charged hadron multiplicity distribution and
photon-hadron azimuthal correlations. Using the running-coupling
Balitsky-Kovchegov evolution equation for calculating various observables, we
show that the main source of uncertainties is due to less constrained initial
nuclear saturation scale. This gives rise to rather large theoretical
uncertainties for nuclear modification factor R_{pA} at the LHC. Nevertheless,
we propose a simple scheme in which one can still test the main dynamics of the
CGC/saturation in p+A collisions at the LHC.
