Probing CP Violation Via Higgs Decays to Four Leptons
A. Soni, R. M. Xu
Abstract
Since decays to four leptons is widely considered a promising way to search for the Higgs particle, we show how the same final state can also be used to search for signals of CP nonconservation. Energy asymmetries and triple correlations are related to parameters in the underlying CP violating effective interaction at the H0-W-W and H0-Z-Z vertex. Expected size of the effects are shown to be small for both the Sandard Model and its extension with an extra Higgs doublet.
