Studying the scalar bound states of K\bar K system in Bethe-Salpeter formalism

Name: Work Video:
Duration: 3 min 30 s
Description: We study the possible bound states of the $Kar K$ system in the Bethe-Salpeter formalism in the ladder and instantaneous approximations. We find that the bound states exist. However, these bound states have very small decay widths. Therefore, besides the possible $Kar K$ component, there may be some other structures in the observed $f_0(980)$ and $a_0(980)$ .
