A Study of Angular Correlations in $\Phi \to ZZ \to 2e2\mu$

The Standard Model predicts an existence of one scalar Higgs boson, while in more general electroweak theory there could be Higgs particles that have different CP-parity and spin. When such hypothetical particles decay into two vector bosons and then into two fermion pairs, angular correlations of t...

description The Standard Model predicts an existence of one scalar Higgs boson, while in more general electroweak theory there could be Higgs particles that have different CP-parity and spin. When such hypothetical particles decay into two vector bosons and then into two fermion pairs, angular correlations of the latter can be used to distinguish between different possible CP-parities and spins. This note describes a study on the possible measurement at CMS of the CP-parity of the Higgs boson using angular correlations in the H->ZZ->2e2mu process, which is a "golden channel'' for the Higgs boson searches at LHC. It will be shown that a measurement of the parameter describing a generalized HZZ coupling, which determines CP-parity of the Higgs boson, will be feasible at CMS. The precision of the measurement is sufficient for determination of CP-parity of the Higgs boson, in particular to distinguish between the scalar and pseudoscalar Higgs bosons.
