摘要：

We determine the neutralino and chargino masses in the MSSM at one loop. We Perform a Feynman diagram calculation in the on-shell renormalization scheme, including quark-squark and lepton-slepton loops. We find generically the corrections are of the order of 5%. For a 20 GeV neutralino the corrections can be as large as 20%. The corrections change the region of mu, M2, tanbeta parameter space which is ruled out by CERN LEP data. We demonstrate that, e.g., for a given mu and tanbeta the lower limit on the parameter M2 can shift by 20 GeV.
