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 u γ and c u l+ l- transitions. Standard Model and New Physics contributions are reviewed for inclusive and exclusive D Vγ, D+ π+ l+ l-, D l+ l- decays. Observables important for search of New Physics are discussed. Possibility to observe CP violation in rare charm decays is questioned.
