英文摘要: We investigated the Drell-Yan process of the light neutralino pair <(chi)over tilde>(0)(i)<(chi)over tilde>(0)(j) (i, j = 1, 2) productions at hadron colliders. We studied the dependence of the coupling properties of two light neutralinos <(chi)over tilde>(0)(1,2) on three SUSY Lagrangian parameters M-1, M-2 and mu, and find that the production rate of <(chi)over tilde>(0)(1)<(chi)over tilde>(0)(2) pair will be dominated by the Higgsino-like couplings under the conditions mu << M-2 and mu similar to M-1, while the productions of <(chi)over tilde>(0)(1)<(chi)over tilde>(0)(1) and <(chi)over tilde>(0)(2)<(chi)over tilde>(0)(2) pairs will be enhanced by the gaugino-like couplings under M-i << mu. For the Higgsino-like <(chi)over tilde>(0)(1,2) neutralinos, the cross section of <(chi)over tilde>(0)(1)<(chi)over tilde>(0)(2) production at the LHC can reach 100 fb.
