Excited Charmed Mesons: Observations, Analyses and Puzzles

Abstract

We review the status of recently observed positive parity charmed resonances, both in the non-strange and in the strange sector. We describe the experimental findings, the main theoretical analyses and the open problems deserving further investigations.
