Towards an understanding of the new charm and charm-strange mesons
The observation of the DsJ*(2317), DsJ(2460), and SELEX DsJ*(2632) states with properties differing considerably from what was expected has led to a renewed interest in hadron spectroscopy. In addition to these states, non-strange partners of the D sJ states have also been observed. Understanding the D 0* and D1 ′ states can provide important insights into the DsJ states. In this contribution I examine quark model predictions for the D0* and D 1 ′ states and discuss experimental measurements that can shed light on them. I find that these states are well described as the broad, j ≤ 1/2 non-strange charmed P-wave mesons. In the latter part of this writeup I discuss the cs̄ possibilities for the SELEX DsJ* (2632) and measurements that can shed light on it.
