We can search the Standard Model (SM) Higgs boson in several capable production channels and decay modes. Our target MH region is [100,150] GeV/c2 which we call low-mass search region because MH = 89+35-26 GeV/c2 (68% confidence level) as of July 2010, as which top quark mass and W boson mass constrain, indirectly. In the low-mass search region the standard model Higgs boson dominantly decays into b quark pair, but it can also decay into a Tau pair (~7% for MH = 120 GeV/c2).

 Here, we show the results of a search for the standard model Higgs boson associated with vector boson using all leptonic decay modes. The final states considered are lν+ττ and ll+ττ.
