Mass Spectrum of 1 P 1 1 Meson State and Mixing Angle of Strange Axial-Vector Mesons

Abstract

In the presence of the b 1 (1235), h 1 (1170), D 1 (2420), and D s1 (2536)± being the members of the 1 P 1 1 meson multiplet, we investigate the mass spectrum of the 1 P 1 1 meson state and the mixing angle of strange axial-vector mesons in the framework of meson-meson mass mixing and Regge phenomenology. Also, in the glueball dominance picture, the kaon is phenomenologically determined to have a mass of about 1356 MeV. The results are compared with the values from different phenomenological models and may be useful for the assignment of the 1 P 1 1 meson multiplet in the future.
