  A new particle of mass around 125 GeV is known to have loop induced couplings
to $gg$ and $\gamma\gamma$. More specific to the Higgs interpretation are tree
level couplings to $W$ and $Z$. A small but clean signal of the Higgs coupling
to $W$ arises from associated production of a Higgs, with
$H\rightarrow\gamma\gamma$. We consider this signal in light of a large NLO
enhancement of the irreducible background.
