Theory seminar: CP-violation, the Neutron Electric Dipole Moment, and New Physics

Jan Olav Eeg, UiO

Recent measurements for direct CP-violation in decays of neutral charmed mesons (explicitly D⁰-> K⁺ + K^- and/or D⁰ -> π⁺ + π^- ) might indicate the existence of New Physics beyond the Standard Model.  A concrete model to explain the effect is proposed by Altmannshofer et al. This model, based on a colored flavor changing scalar, will also generate  a new contribution to the electric dipole  moment of the neutron (NEDM).   I present a calculation for this quantity within the proposed  New Physics model. The calculation shows that the obtained value for the  NEDM within the model is close  to its experimental bound.
