Search for chargino and neutralino productionat $\sqrt{s} = 192$ -209 GeV at LEP

2004 European Physical Journal C: Particles and Fields  
Approximately 438 pb −1 of e + e − data from the OPAL detector, taken with the LEP collider running at centre-of-mass energies of 192-209 GeV, are analyzed to search for evidence of chargino pair production, e + e − →χ + 1χ −
