| 英文摘要 | In this work, the K (K) over bar* interaction is studied in a quasipotential Bethe-Salpeter equation approach combined with the one-boson-exchange model. With the help of the hidden-gauge Lagrangian, the exchanges of pseudoscalar mesons (pi and eta) and vector mesons (rho, omega and phi) are considered to describe the K (K) over bar* interaction. Besides the direct vector-meson exchange which can be related to the WeinbergTomozawa term, pseudoscalar-meson exchanges also play important roles in the mechanism of the K _ K* interaction. The poles of scattering amplitude are searched to find the molecular states produced from the K (K) over bar* interaction. In the case of quantum number I-G (J(PC)) = 0(+)(1(++)), a pole is found with a reasonable cutoff, which can be related to the f(1)(1285) in experiment. Another bound state with 0(-)(1(+)-) is also produced from the K (K) over bar* interaction, which can be related to the h(1)(1380). In the isovector sector, the interaction is much weaker and a bound state with 1(+)(1(+)) relevant to the b(1)(1235) is produced but at a larger cutoff. Our results suggest that in the hadronic molecular state picture the f(1)(1285) and b(1)(1235) are the strange partners of the X(3872) and Z(c)(3900), respectively. |
