Description | Joint Theory Seminar Speaker: Yuhsin Tsai (UC Davis) Title: Baryogenesis and Superparter Oscillations in R-symmetric SUSY Host: Yuhsin Tsai Room: 432 Abstract: Weak scale SUSY with R-symmetry is a plausible solution to the SUSY flavor problem. In this talk, we discuss two interesting aspects of R-symmetric SUSY models: electroweak baryogenesis and superpartner oscillations. Regarding baryogenesis, the new superpotential couplings between the adjoints and the Higgs can increase the strength of the electroweak phase transition, and large CP-violating phases consistent with electric dipole moments can generate large baryon asymmetry. R-symmetric models can also give spectacular signals at the LHC. If a tiny Majorana mass splits the degenerate mass eigenstates of gauginos and higgsinos, states produced at the LHC can oscillate between the spraticles and their Dirac mass partners. With displaced decays, the oscillation can be visible in the distribution of displaced vertex lengths at the LHC. |
