MESON SPECTROSCOPY IN THE HEAVY STRATON MODEL

【摘要】 <正> Assuming that the bare mass of the straton is very large and that the interaction of the straton and antistraton is instantaneous in the rest frame of the meson and taking the form of V₀ γ,×γ₅+V₁γ₄×γ₄×V₂γ×γ, we solve the B-S equation for mesons. The mass formula m²=（m₁+m₂）²+2（m₁+m₂）E is obtained, where m₁ （m₂） is the effective mass of the straton （antistraton） inside the meson and E is the eigenvalue of the Schrdinger equation. The obtained mass spectra including both light mesons and heavy mesons agrce with experimental data. Our model may provide a possille explanation for the question why the nonrelativistic Schrdinger equation can be used even for hadronic systems composed of u, d, s stratons, though their effective mass is very small.更多还原
