Determining the Neutral D Mixing Parameters

Abstract

Evidence for mixing in the neutral D meson system has recently been reported. Assuming negligible CP violation, non-vanishing width and mass differences between the two neutral D mass eigenstates has been found. Theoretical predictions of these are rather difficult, obscuring detection of New Physics contributions. However, the observation of CP violation in the D system would be a good signal of New Physics. We briefly describe the formalism that describes the neutral D decay and mixing, and present a method to determine all the mixing parameters accurately allowing for arbitrary CP violation.
