Angular correlations and CP asymmetries in the decay Φ → ZZ → 4 fermions
We investigate the possibility of detecting effects of CP violation in the process Φ → ZZ → 4 fermions for a most general of Φ ZZ coupling of a Higgs boson with a spin zero with a pair of Z bosons. Moreover, as the amplitude of the Φ → ZZ decay we used its representation in terms of the linear polar...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We investigate the possibility of detecting effects of CP violation in the process Φ → ZZ → 4 fermions for a most general of Φ ZZ coupling of a Higgs boson with a spin zero with a pair of Z bosons. Moreover, as the amplitude of the Φ → ZZ decay we used its representation in terms of the linear polarization of the vector bosons. We have considered asymmetries that can be signal of CP violation and have estimated their sizes. It is shown, that measurement of angular correlations is important both for the test of the Standard Model, and for search of effects of new physics at the TeV scale. |
