T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

In this talk, anomaly free Abelian discrete symmetries of the MSSM are considered that forbid the μ-term at perturbative order. Allowing for anomaly cancellation via the Green-Schwarz mechanism discrete R-symmetries are identified as the only possibility and it is proven that there is a unique Z_4R symmetry that commutes with SO(10). Furthermore, it is argued that non-perturbative effects will...

The Randall-Sundrum model features one compact extra dimension and is suitable for stabilizing the electroweak scale. I discuss its interesting phenomenological implications for CP violation in kaon mixing and rare decays and the interplay between different observables, with remarks on model-specific protection mechanisms. I also comment on possible effects from deviations in the Higgs...

8. Suppression of flavor violation in an A4 warped extra dimensional model

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

We recently proposed a model (JHEP08(2010)115) based on the non abelian discrete flavor group A4 implemented in a custodial RS setup with a bulk Higgs. We showed that the standard model flavor structure can be realized within the ZMA (zero mode approximation), with nearly TBM neutrino mixing and a realistic CKM matrix with rather mild assumptions. An important advantage of this framework...

21. CP violating Higgs sector of MSSM

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

Many couplings in the MSSM, like the tri-linear couplings, the mass parameter, mu, etc. could in general be complex quantities, leaving a CP-violating Higgs sector. In such case the physical Higgs bosons will not be CP-eigenstates, leading to very different phenomenology compared to the CP-conserving MSSM. We explore the di-photon decay channel of the Higgs bosons within this context at the...
