Boost to h→Zγ : from LHC to future e+e− colliders.

No, Jose Miguel and Spannowsky, Michael (2017) 'Boost to h→Zγ : from LHC to future e+e− colliders.', Physical review D., 95 (1). 075027.

Abstract

A precise measurement of the Higgs h→Zγ decay is very challenging at the LHC, due to the very low %SM h→Zγ(Z→ℓℓ) branching fraction and the shortage of kinematic handles to suppress the large SM Zγ background. We show how such a measurement would be significantly improved by considering Higgs production in association with a hard jet. We compare the prospective HL-LHC sensitivity in this channel with other Higgs production modes where h is fairly boosted, e.g.~weak boson fusion, and also to the potential h→Zγ measurement achievable with a future e+e− circular collider ({\sl fcc-ee}). Finally, we discuss new physics implications of a precision measurement of h→Zγ.
