Abstract

The experimental status of the recently observed resonances which could be interpreted as cqˉ\bar q mesons with slP=1/2+_l^P={1/2}^+ is reviewed. In the framework of HQET and chiral perturbation theory, strong and radiative widths of these states are computed in the hypothesis that they are cqˉ\bar q states, obtaining results consistent with the experimental measurements. Masses and widths for the analogous states containing a beauty quark are also predicted.
