Mass Spectrum of 1P11 Meson State and Mixing Angle of Strange Axial-Vector Mesons

الملخص EN

In the presence of the b1(1235), h1(1170), D1(2420), and Ds1(2536)± being the members of the 1P11 meson multiplet, we investigate the mass spectrum of the 1P11 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 1P11 meson multiplet in the future.
