Dispersive and Absorptive CP Violation in $D^0-\overline{D^0}$ Mixing

Alexander L. Kagan, Luca Silvestrini

CP violation (CPV) in $D^0-\overline{D^0}$ mixing is described in terms of the dispersive and absorptive `weak phases' ${\varphi }_f^M$ and ${\varphi }_f^{\Gamma }$. They parametrize CPV originating from th…
