Deconstructing angular correlations in (Formula Presented) and (Formula Presented) production at CERN LEP 2

Research output: Contribution to journalArticle


We apply a generalized spin-basis analysis to associated Higgs boson production and gauge boson pair production at CERN LEP. This framework allows us to identify a choice of spin axes for the processes (Formula presented) (Formula presented) which leads to strikingly different correlations among the decay products, even well above threshold. This spin basis optimizes the difference in the angular correlations for these two processes. In contrast, the same distributions display little contrast when the helicity basis is used. We also apply this technique to the case of (Formula presented) boson pair production.
