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 √s=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.展开更多
文摘This paper mainly investigates the semicontinuity of solution mappings for set optimization problems under a partial order set relation instead of upper and lower set less order relations.

Then, we give some sufficient conditions for the semicontinuity and closedness of solution mappings for parametric set optimization problems.
