Flavor Changing Neutral Currents in Charm Sector
S. Pakvasa
Abstract
I would like to discuss D0-D0 the mixing and rare D decays as manifestations of Flavor Changing Neutral Currents (FCNC) in the charm sector. I will first review the expectations in the Standard Model (SM) and then summarize some typical expectations in new physics scenarios. I would like to argue that the charm case offers a large window of opportunity and it may be possible to learn something about the origin of the fermion mass matrix.
