Abstract

Based on the relations derived from the Regge phenomenology, we investigate the mass spectrum of radial excitation of tensor meson nonet. The results suggest that the states f 2 (1810), f 2 (2010) and K * 2 (1980) should be assigned as the first radial excitation of tensor meson. Our prediction can be useful for the assignment of tensor meson nonet in the future.

Mass formulas for single-charm tetraquarks with Fermi-Breit hyperfine interaction

“…As one can see from Table 2 in Ref. [44] or Table 2 in Ref. [45] and from references therein, our predictions for constituent quark masses are similar to masses obtained using different phenomenological models.…”
