Indirect search for lepton flavour violation at CERN LEP via doubly charged bileptons

We search for lepton flavour violating couplings via doubly charged bilepton (or doubly charged Higgs) exchange in electron-positron annihilation process $ \text{e}^{+}\text{e}^{-}\to \mu^{+}\mu^{-}, \tau^{+}\tau^{-}$ using CERN LEP data at the center of mass energies between 189-207 GeV. Standard m...

description We search for lepton flavour violating couplings via doubly charged bilepton (or doubly charged Higgs) exchange in electron-positron annihilation process $ \text{e}^{+}\text{e}^{-}\to \mu^{+}\mu^{-}, \tau^{+}\tau^{-}$ using CERN LEP data at the center of mass energies between 189-207 GeV. Standard model program ZFITTER has been used to calculate radiative corrections. We find that $g_{L}^{2}/M_{L}^{2}<O(10^{-6})GeV^{-2}$ at 95% C.L. for flavour violating scalar and vector bilepton couplings.
