This feasibility study concerns the implementation and analysis of a Higgs pair decaying to two W bosons, with hadronic final states, and to two τ-leptons, one with a leptonic and one with a hadronic final state, hh→ WhadWhad τlepτhad, in the ATLAS detector at the CERN Large Hadron Collider, by adapting the ``CxAOD framework'' software analysis code of the hh→ bbττ analysis. The purpose is to compare the sensitivity of this final state with other di-Higgs analyses in the ATLAS collaboration. Monte Carlo samples are used for the background and signal simulation. A cut based selection is then performed based on several kinematic variables. Finally, a statistical analysis is performed on the MMC mass distribution of the ττ system. The cross section can be limited at the 95 % confidence level to σexpected < 89.8 fb, compared to the theoretical σSM = 0.19 fb.
