New physics and signal-background interference in associated pp → HZ production

Englert, Christoph; Rosenfeld, Rogerio; Spannowsky, Michael; Tonero, Alberto

Abstract

We re-investigate electroweak signal-background interference in associated Higgs production via gluon fusion in the presence of new physics in the top Higgs sector. Considering the full final state $pp \to b \bar b \ell^+\ell^-~(\ell=e,\mu)$ , we discuss how new physics in the top Higgs sector that enhances the ZZ component can leave footprints in the HZ limit setting. In passing we investigate the phenomenology of a class of new physics interactions that can be genuinely studied in this process.
