摘要：

The production of a neutralino pair via gluon-gluon fusion is studied in the minimal supersymmetric model (MSSM) at proton-proton colliders. The numerical analysis of their production rates is carried out in the MSUGRA scenario. The results show that this cross section may reach about 80 fb fur <(chi)over tilde>(0)(1)<(chi)over tilde>(0)(2) pair production and 23 fb for <(chi)over tilde>(0)(2)<(chi)over tilde>(0)(2) pair production with suitable input parameters at the future CERN LHC collider. It shows that this loop-mediated process can be competitive with the quark-antiquark annihilation process at the LHC.
