In this contribution we study the production of squarks. If squarks are found in proton-proton (pp) collisions at the LHC, they might also be produced in collisions involving nuclei (pA and AA collisions). Here we investigate the influence of nuclear effects in the production of squarks in nuclear collisions at the LHC, and estimate the transverse momentum dependence of the nuclear ratios R{sub pA} = (d{sigma}(pA)/d{sub pT})/A(d{sigma}(pp)/d{sub pT}) and R{sub AA} = (d{sigma}(AA)/d{sub pT})/A{sup 2}(d{sigma}(pp)/d{sub pT}). We demonstrate that depending on the magnitude of the nuclear effects, the production of squarks could be enhanced or suppressed, compared to proton-proton collisions at same energies.
