Jet production at next-to-leading order in p+Au collisions at the RHIC

We calculate jet productions in p+Au collisions at the RHIC at next-to-leading order with perturbative QCD.Inclusive jet transverse energy spectrum,dijet invariant mass spectrum,dijet angular distribution,and corresponding nuclear modification factors for the three observables in p+Au collisions at 8;= 200 GeV are given,where the initial-state cold nuclear matter（CNM） effects are included by taking advantage of four parametrization sets of nuclear parton distribution functions（nPDFs）-EPS,nCTEQ,HKN and DS.We demonstrate that inclusive jet transverse energy（ET） spectrum,dijet invariant mass（MJJ） spectrum with all 4 nPDFs are increased at low ET or MJJ,whereas at high ET or MJJ large deviation of results with different nPDFs is observed.It is found that the dijet angular distributions in p+Au collisions do not vary relative to those in p+p collisions for all 4 nPDFs.
