Possibility of measuring the magnetic moment of theWboson at heavy-ion colliders

We consider the possibility of measuring the magnetic moment at the W boson at a heavy-ion collider. We find that the cross section for the process $Pb+Pb{→}{γ}{γ}{→}{e}^{±{}}{{ν}}ₑ{{μ}}^{{∓}}{{ν}}_{{μ}}$ is very sensitive to this parameter and that a $3{σ}$ measurement of 35% seems possible at the CERN Large Hadron Collider and a precision of 8% or so at the Superconducting Super Collider, given an integrated luminosity of 0.1 ${pb}^{{-}1}$.
