The search is conducted by looking for a localized excess in the W H/Z H invariant or transverse mass distribution. No significant excess is observed, and the results are interpreted in terms of constraints on a simplified model based on a phenomenological Lagrangian of heavy vector triplets.Facultad de Ciencias Exactas
