Résumé

A search for a new resonance decaying to a $W$ or $Z$ boson and a Higgs boson in the $\ell \ell/ \ell \nu/ \nu \nu + b \bar{b}$ final states is performed using 20.3 fb$^{-1}$ of $pp$ collision data recorded at $\sqrt{s}=$ 8 TeV with the ATLAS detector at the Large Hadron Collider. The search is conducted by examining the $WH/ZH$ invariant mass distribution for a localized excess. No significant deviation from the Standard Model background prediction is observed. The results are interpreted in terms of constraints on the Minimal Walking Technicolor model and on a simplified approach based on a phenomenological Lagrangian of Heavy Vector Triplets.
