摘要：

In this paper, we investigate the influence of nuclear effects in the production of gluinos in nuclear collisions at the Large Hadron Collider, and estimate the transverse momentum dependence of the nuclear ratios R-pA = d sigma(pA)/dyd(2)pT / A d sigma(pp)/dyd(2)pT and R-AA = d sigma(AA)/dyd(2)pT / A(2) d sigma(pp)/dyd(2)pT. We demonstrate that depending on the magnitude of the nuclear effects, the production of gluinos could be enhanced, compared to proton-proton collisions. The study of these observables can be useful to determine the magnitude of the shadowing and antishadowing effects in the nuclear gluon distribution. Moreover, we test different snowmass points and slopes scenarios, corresponding to different soft, supersymmetry breaking mechanisms, and find that the nuclear ratios are strongly dependent on that choice.
