Violation Of The $\Delta I=1/2$ Rule In $D\to \pi \pi$ Decays

Abstract

A strong violation of the $\Delta I=\frac{1}{2}$ rule has experimentally been found in the $D\to \pi \pi$ decays [1]. In this letter we will show that the order of magnitude of this violation can be understood in terms of the pure quantum chromo dynamics corrections to the weak interactions.
