Implication of the D Width Difference On CP-Violation in D-D̄ Mixing


Both BaBar and Belle have found evidence for a non-zero width difference in the D-D̄ system. Although there is no direct experimental evidence for CP-violation in D mixing (yet), we show that the measured values of the width difference y ∼ ∆Γ already imply constraints on the CP-odd phase in D mixing, which, if significantly different from zero, would be an… (More)
