Theoretical perspective on rare and radiative charm decays

Abstract

Recent experimental bounds on rare charm decays offer a chance to improve our theoretical understanding of physics present in $c\to u\gamma$ and $c\to u{l}^{+}{l}^{-}$ transitions. Standard Model and New Physics contributions are reviewed for inclusive and exclusive $D\to V\gamma$, $D^{+}\to {\pi }^{+}{l}^{+}{l}^{-}$, $D\to l^{+}{l}^{-}$ decays. Observables important for search of New Physics are discussed. Possibility to observe CP violation in rare charm decays is questioned.
