Charge asymmetries in γγ to μ^+μ^- + ν_(μ) bar{ν}_μ / γ γ to W^pmμ^mp +ν_μ with polarized photons

It is shown that the difference in the distributions of positive ($\mu^+$) and negative charged leptons ($\mu^-$) in reactions $\gamma \gamma \to \mu^+\mu^-+\nu\bar\nu$ and $\gamma \gamma \to W^\pm\mu^\mp +\nu(\bar\nu)$ at $\sqrt{s}>200$ GeV leads to observable {\em charge asymmetry} of muons which is sensitive to New Physics effects.
