Abstract
We have calculated the mass spectrum of 
mesons within a nonrelativistic potential model considering coupled channel effects, and the corresponding strong decay widths within the 
model using the numerically calculated wave functions. By comparing with the available experimental data, we find that the states , 
, 
, and 
could be interpreted as the 
, 
, 
, and 
, respectively. Although the quantum numbers of the newly observed 
and 
states have not been determined, our results support the assignments of 
and 
for them. Our predictions are helpful in searching for the bottom-strange meson in future experiments.
