Description
The HH → bbττ channel is among the most sensitive final states for probing Higgs boson pair production at the LHC, benefiting from the large H → bb branching fraction and the clean signatures of τ decays. The analysis is nevertheless challenged by significant backgrounds from $t\bar{t}$, Z+heavy flavour, single-Higgs production, and multijet processes. This poster presents the inclusive analysis strategy, detailing the background modelling and the multivariate techniques used to define signal and control regions and to enhance signal discrimination. The latest results are presented and discussed, with emphasis on the upper limit set on the Higgs boson pair production signal strength (μ_{HH}) and constraints on Higgs self-coupling parameters ($κ_λ$ and $κ_{2V}$).
