Abstract

Basic idea of $CP$ violation and its importance for cosmology, Standard Model and possible New Physics are introduced. Recent (2019) discovery of CP violation in charm in the $\Delta A_{CP}$ between $D^0\rightarrow K^-K^+$ and $D^0\rightarrow \pi^+\pi^-$ decay channels and evidence for direct CP violation in $D^0\rightarrow \pi^-\pi^+$ decays in 2023 is discussed. Motivation and brief outline for search of CP violation in the $D^0\rightarrow V\gamma$, where $V=\phi,\rho^0, \bar{K}^{*0}$ decays is given.
