Recently,the mixing of scalar mesons was introduced into the chiral SU(3) quark model and also dynamically applied to the baryon-baryon system.The results show that the nucleon-nucleon and hyperon-nucleon scattering data can be reasonably described for different mixing cases,one is ideal mixing and the other is θs =19° mixing.In the present work,by taking the above parameters,the possible candidate of deltaron bound state is further predicted.We find that the contributions from σ and (e) exchange to binding energy of deltaron are different,that the contribution from ∈ exchange is negligible,and that σ exchange is dominant.We also find that the binding energy ot deltaron is very stable,around several tens of MeV,no matter what kind of mixing is adopted.
