Implications of the evidence for direct $\mathbf{CP}$ violation in $D\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}$ decays

Rahul Sinha, Thomas E. Browder, N. G. Deshpande +2

The observation of $CP$ violation in the difference of $CP$ asymmetries between $D\to K^{+}{K}^{-}$ and $D\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}$ has raised a debate whether the observed asymmetries can be regard…
