Charge asymmetry in $\mathbf{\gamma \gamma }\to {\mathbf{\mu }}^{+}{\mathbf{\mu }}^{-}+\mathbf{neutrinos}$ with polarized photons

Abstract

The difference in distributions of ${\mu }^{+}$ and ${\mu }^{-}$ in reactions $\gamma \gamma \to {\mu }^{+}{\mu }^{-}+\nu \bar{\nu }$ and $\gamma \gamma \to W^{\pm }{\mu }^{\mp }+\nu (\bar{\nu })$ with polarized photons at $\sqrt{s}>200$ GeV is a large observable effect which is sensitive to New Physics phenomena.
