Abstract content <br> &nbsp; (Max 300 words)

In gluon fusion and vector boson fusion Higgs production, the H→WW(*) cross section x branching ratio is relatively large in the mass region 120 < mH < 240 GeV (which spans the range still allowed after precision electroweak and LHC exclusions). The backgrounds for this decay channel are also well understood, so a sensitive search is possible. The ATLAS H→ WW results up to now contain only the ee, μμ, and eμ channels, and we extend the search sensitivity in the low Higgs mass region to include the eτ and μτ channels, where the τ decays hadronically. We present a first look at this decay channel using the 2011 7 TeV data from ATLAS at the LHC.
