If one of the recently discovered charmed-strange mesons (D_sJ(2317)) is the 0+ state of cs-bar, the other (D_sJ(2460)) is most likely the 1+ state with j=1/2. They could be produced in e+e- annihilation by fragmentation from cc-bar jets or as decay products of B mesons. If one analyzes the cc-bar jet events and the B decay events separately, one will have a direct test as to whether D_sJ(2460) is the j=1/2 state or not, how much D_sJ(2460) is mixed with the j=3/2 state, and whether the four-quark interpretation is viable.
