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

The Higgs to ΖZ(∗) to l+l-l+l- decay channel has good signal to background ratio and can be used to reconstruct the Higgs invariant mass with quite good resolution for an intermediate mass range Higgs ( mΖ < mH < 2mΖ ). This makes the ΖΖ(∗) channel one the most relevant channels to study at the LHC, where it has been found that mH≈125 GeV . Although the Higgs to ΖΖ(∗) decay channel played an important role in this discovery, the decay leptons considered excluded Ζ bosons decaying into τ leptons. Reasons for this lie in the hard-to-detect hadronic or leptonic τ decays. A study which includes Ζ decaying into τ is beneficial to completing the picture of the Higgs search, particularly in the statistically limited vector-boson-fusion like search. Preliminary results of the search for Higgs channel Η→ΖZ(∗)→τ+ τ- l+l-, (l = e or μ) will be presented and discussed.
