Rare D decays

Rare D meson decays serve as powerful tools to study flavor-changing neutral-current in the up-type quark sector, to test the Standard Model and search for new physics through enhancements in decay rates, CP asymmetries or angular observables. LHCb, Belle and BESIII are the major experiments for charm physics bearing a vast discovery potential. This talk summarizes the most recent results on the rare D mesons decay measurements at LHCb, Belle and BESIII experiments, the lessons learned and gives a brief outlook to future prospects.
