Abstract

Based on the main assumption that a ₀(980) and D ^* _sJ(2317) belong to the 1³ P ₀ q¯ multiplet, in the framework of Regge phenomenology and meson-meson mixing, it is suggested that a ₀(980), K ^* ₀(1052), f ₀(1099) and f ₀(530) constitute the ground scalar meson nonet, and that the f ₀(1099) is composed mostly of s¯, while the f ₀(530) is mainly a u¯ + d¯ system. It is supposed that these states would likely correspond to the observed scalar states a ₀(980), κ(900), f ₀(980) and f ₀(600)/σ, respectively. The agreement between the present findings and those given by other different approaches is satisfactory.
