Higgs boson to di-tau channel in Chargino-Neutralino searches at the LHC

Understand

We consider chargino-neutralino production, $\tilde{\chi}_2^0 \tilde{\chi}_1^\pm \to (h \tilde{\chi}_1^0)(W^\pm \tilde{\chi}_1^0)$, which results in Higgs boson final states that subsequently decay (inclusively) to leptons (either $h\rightarrow \tau^+\tau^-$ or $h\rightarrow W^+W^- \to (e^+e^-, \mu^+\mu^-, \tau^+\tau^-)+E_T^\mathrm{miss}$).

• Such channels are dominant in large regions of the allowed supersymmetric parameter space for many concrete supersymmetric models.
• The existence of leptons allows for good control over the backgrounds, rendering this channel competitive to the conventional $h\rightarrow b\bar{b}$ channel that has been previously used to impose constraints.
• We include hadronic decays of the $\tau$ leptons in our analysis through a $\tau$-identification algorithm.
