Search for Chargino and neutralino                                             
Production at sqrt(s)=192-202 GeV at LEP                                       
  
A search for charginos and neutralinos,                                        
predicted by supersymmetric theories, is                                       
performed using a data sample of 214 inverse pico-barns                        
taken at a centre-of-mass energy of 192-202 GeV                                
with the OPAL detector at LEP.                                                 
A likelihood technique is used to optimize the                                 
analysis sensitivity, using an interpolation technique to                      
construct signal kinematic distributions at arbitrary                          
chargino and neutralino masses.                                                
Upper limits on chargino and neutralino pair production                        
cross-sections are obtained                                                    
as a function of the chargino mass,                                            
the lightest neutralino mass                                                   
and the second lightest neutralino mass.                                       
Limits on the chargino and neutralino masses                                   
are inferred                                                                   
within the Constrained Minimal Supersymmetric Standard Model                   
framework.
