Abstract
We calculate the masses and the strong decays of orbitally excited states , , and by the improved Bethe-Salpeter method. The predicted masses of and are , . We calculate the isospin symmetry violating decay processes and through mixing and get small widths. Considering the uncertainties of the masses, for and , we also calculate the OZI allowed decay channels: and . For and , the OZI allowed decay channels , and are studied. In all the decay channels, the reduction formula, PCAC relation and low energy theorem are used to estimate the decay widths. We also obtain the strong coupling constants , , , , , , , , and .
