Dear All,
We have the pleasure of inviting you to the Particle Theory Seminar on Tuesday,

Search for effects beyond the Standard Model in some decays of the Higgs boson".


Effects of possible CP violation in the Higgs-boson decays to (i) two photons, (ii) photon and Z boson, (iii) photon and a pair of leptons, are studied with a particular emphasis on polarization effects. We also discuss a hypothetical non-Hermiticity of the Yukawa interaction of the Higgs boson with fermions. The influence of the non-Hermiticity on the Higgs decay to a pair of polarized tau leptons is investigated. The longitudinal polarization of tau lepton is shown to be a direct measure of the CP violation and non-Hermiticity of the Yukawa interaction. The contributions to the longitudinal polarization of leptons and quarks that arise due to the loop corrections with the Hermitian interaction are also evaluated.


The speaker will be on-site, local participants are invited to meet in the seminar room D-2-02.
