摘要：
We investigate the production of neutralino pairs via photon-photon collisions in the minimal supersymmetric model at future linear colliders. The numerical analysis of their production rates is carried out in the minimal supergravity scenario. The results show that this cross section can reach about 18 fb for (chi) over tilde (0)(1)(chi) over tilde (0)(2) pair production and 9 fb barn for (chi) over tilde (0)(2)(chi) over tilde (0)(2) pair production with our chosen input parameters.
