All-hadronic HZ production at high energy at 3 TeV CLIC

Abstract

In this note the $\mathrm{HZ}$ production in the all-hadronic final state in $\mathrm{e}^{+}\mathrm{e}^{-}$ collisions at the Compact Linear Collider is studied at the 3 TeV stage. At high energies, the events have an experimental signature of back-to-back approximately mono-energetic large jets. Each of these jets contains two sub-jets and substructure compatible with two original objects. The study is based on full simulation including the detector response, as well as the presence of beam-induced background from $\gamma\gamma\to\mathrm{hadrons}$. Results on the measurement of the total $\mathrm{HZ}$ cross section are given, and the potential to measure angular asymmetry observables is discussed.
