Multiple parton scatterings in high-energy p A collisions involve multiparton correlation inside the projectile and color coherence of multiple jets, which will lead to nuclear modification of final hadron spectra relative to that in p p collisions. Such modifications of final hadron spectra in p A collisions are studied within the HIJING 2.1 model. Besides parton shadowing and transverse momentum broadening, which influence final hadron spectra at intermediate p(T), modification of parton flavor composition due to multiple scattering and hadronization of many-parton jets system are shown to lead to suppression of final hadrons at large p(T) in p A collisions at the CERN Large Hadron Collider.
