Leptonic final states from di-boson production at the LHC in the 4-dimensional composite Higgs model

A bstract We study di-boson production via both neutral and charged current at the Large Hadron Collider, i.e. subprocesses and , respectively, where q , q ′ are quarks and l , l ′ = e , μ , in all possible combinations, in the context of the 4-Dimensional Composite Higgs Model.

Description
Summary:A bstract We study di-boson production via both neutral and charged current at the Large Hadron Collider, i.e. subprocesses and , respectively, where q , q ′ are quarks and l , l ′ = e , μ , in all possible combinations, in the context of the 4-Dimensional Composite Higgs Model. These modes enable the production in the intermediate steps of several additional — with respect to the Standard Model — neutral and charged gauge bosons belonging to the spectrum of this scenario, all of which in resonant topologies. We not only find these channels to be accessible over the background but also show that, after a dedicated cut-based analysis, kinematic reconstruction of most such resonances is always possible. However, since the Electro-Weak precision data generally disfavor neutral and charged gauge boson masses below the TeV range and also their large couplings to light-fermions, these modes turn out to be relevant only for the 14 TeV option with high integrated luminosity.
