Abstract

The mass spectrum of P-wave mesons is considered in a nonrelativisticconstituent quark model. The results show the common mass degeneracy of the isovector and isodoublet states of the scalar and tensor meson nonets, m(a(0))congruent to m(a(2)), m(K-0)congruent to m(K-2*), and do not exclude the possibility of a similar degeneracy of the same states of the axial-vector and pseudovector nonets. Current experimental hadronic and tau-decay data suggest, however, a different scenario leading to the a(1) meson mass similar or equal to 1190 MeV and the K-1A-K-1B mixing angle = (37 +/- 3)degrees. Possible s (s) over bar states of the foul nonets are also discussed.
