Constraints onR-parity violating couplings from CERN LEP and SLAC SLD hadronic observables
Physical Review D, Particles and fields
We analyze the one loop corrections to hadronic Z decays in an R-parity violating extension to the Minimal Supersymmetric Standard Model (MSSM). Performing a global fit to all the hadronic observables at the Z-peak, we obtain stringent constraints on the R-violating couplings constants lambda' and lambda". As a result of the strong constraints from the b asymmetry parameters A_b and A_FB(b), we find that the couplings lambda'i31, lambda'i32, and lambda"321 are ruled out at the 1 sigma level,doi:10.1103/physrevd.62.015003 fatcat:dp4rquu5e5fgfekwetn6b5lvf4
