摘要：
We interpret the scalar B-s0*(5725) as an S-wave B (K) over bar molecular bound state in the Bethe-Salpeter approach. In the ladder and instantaneous approximation, with the kernel induced by rho and omega exchanges, we establish the Bethe-Salpeter equation for B-s0*(5725). We find that the bound state of B (K) over bar can exist. We also calculate the isospin-violating decay width of the process B-s0*(5725) -> B-s pi(0) through exchanging K-* and B* mesons including the eta-pi(0) mixing effect. We hope that the obtained decay width is instructive for the forthcoming experiment.
