Dear members, We are pleased to announce one more seminar next week. * Title: A complete, calculable, predictive and testable model for all known and required CP violation * Speaker: ChangSub Shin(The State University of New Jersey) * Date: 3:00 PM, January 11 2016 * Place: CTPU Seminar Room, KAIST Munji Campus * Abstract:
We present a complete, calculable, predictive and testable
supersymmetric model for all known and required CP violation. The origin
of all CP violation and flavor mixing in the model is contained in the setup of an SU(5) unified Nelson-Barr mechanism. The
scale of spontaneous CP breaking is taken to be larger than the right
handed (RH) neutrino masses to allow for thermal leptogenesis.
Supersymmetry protects the strong CP phase from dangerous contributions
induced due to the large CP breaking scale. The low energy theory is a supersymmetric type I seesaw model, with all flavor
mixing and CP violating effects contained in a wave function
renormalization matrix. The model acomodates all the measured masses and
mixing angles in the quark and lepton sector, solves the strong CP
problem, predicts the CP violating phases in the PMNS matrix, a normal
neutrino mass hierarchy and the lightest neutrino mass to be in the
window 2 times 10^{−3}
eV < m_{nu 1} < 9.5 times 10^{-3} eV. The observed baryon
asymmetry is obtained through thermal leptogenesis for a RH neutrino
mass 10^9 GeV < M_1 < 10^{11} GeV. The analysis is considerably
simplified by making use of flavor invariants.
We look forward to your participation in the seminars.
Thank you.
Sincerely,
Mijin Kim
