Query: Dalitz Decay $H\to\,f\bar{f}\gamma$ as a Background for
  $H\to\gamma\,\gamma$   The Dalitz decay $H\to\,f\bar{f}\gamma$ is calculated for very small
$f\bar{f}$ invariant masses where the $f\bar{f}$ pair could be mistaken for a
photon in analysis of $H\to\gamma\gamma$ decays. Using the ATLAS cuts and the
full Dalitz decay amplitude, we estimate this fraction to be 7.06%.
