Description

We investigate the flavor changing neutral current bsV(V=$γ$,Z) couplings in the production vertex for the process $e^+e^-\to b\bar s or \bar b s$ in the standard model. The precise calculations keeping all quark masses non-zero are carried out. Production cross sections are found to be the order of $10^{-3}$ fb at LEP II and the order of $10^{-1}$ fb when center-of-mass energy is near the mass of neutral gauge boson Z.
