An attempt to improve signal significance for the Standard Model low mass Higgs
boson produced in WH channel in ATLAS experiment is described in the Note. The
most significant background processes, WZ, W+jets and $\ttbar$, are considered.
The approach exploits the condition for the minimal angular separation in
two-particle decays.
The analysis was not aimed to get the final number of the Higgs over the
background, but to examine some new kinematical cuts and check the potential
improvements.
