The usual comparison between the electroweak part of the standard model and the new experimental results from the LHC ignores the huge, but short lived, magnetic field that is generated during a proton-proton collision. We explain the phenomenon of W condensation, which can occur as a consequence of the magnetic field. This would among other things have an effect on the rate Higgs -> two photons, where preliminary data indicate a deviation from the perturbative rate. We also point out that even if W condensation does not occur, these perturbative calculations should be modified as a consequence of the large magnetic field which influence the relevant W propagators.
