Contribution

It introduces a novel approach to distinguish Higgs spin and CP states through specific production channels, enhancing the analysis of Higgs quantum numbers.

Findings

Weak-boson-fusion can differentiate Higgs spin states.

Associated ZH production helps identify CP properties.

Method improves understanding of Higgs interactions.

Abstract

Recently, the ATLAS and CMS experiments have reported the discovery of a Higgs like resonance at the LHC. The next analysis step will include the determination of its spin and CP quantum numbers or the form of its interaction Lagrangian channel-by-channel. We show how weak-boson-fusion Higgs production and associated ZH production can be used to separate different spin and CP states.
