Charge asymmetry in $\bm{γγ\to μ^+μ^- + neutrinos}$ with polarized photons

Abstract

The difference in distributions of $μ^+$ and $μ^-$ in reactions $γγ\to μ^+μ^-+ν\barν$ and $γγ\to W^\pmμ^\mp +ν(\barν)$ with polarized photons at $\sqrt{s}>200$ GeV is a large observable effect which is sensitive to New Physics phenomena.
