摘要：

We evaluate the supersymmetry reach of the Large Hadron Collider within the gauge-mediated low energy supersymmetry breaking framework, assuming that a neutralino is the second lightest sparticle and that it decays promptly into a gravitino which escapes detection. We find that the maximum reach is obtained via a search for inclusive gamma gamma + E-T events coming dominantly from chargino and neutralino production. Assuming an integrated luminosity of 10 fb(-1), we find that LHC experiments will be able to probe values of the model parameter Lambda less than or similar to 400 TeV, corresponding to m((g) over tilde) less than or equal to 2.8 TeV. A measure of the model parameter,I may be possible from the photon p(T) spectrum. (C) 1998 Elsevier Science B.V. All rights reserved.
