Summary
The hadronic vacuum in the mean field (MF) model is studied on the basis of the soliton model. The overlap of hadronic vacua is given corresponding to the MF potential and calculated explicitly in the case of a Gaussian potential. It is generally understood that the overlap of hadronic vacua is characterized by thearea of MF potential. The meaning of the «local approximation» in the calculation of one-hadron matrix elements is made clear.

The shape of vacuum overlap depends not only on thearea of potential (v 0 r 0) but also on the soliton mass (m σ r 0) as seen in (3.6). It is clear that the vacuum overlap has the same approximate form as (4.6) for a large soliton mass (Case I), which is considered byK. Huang andD. R. Stump for a square-well potential in ref.[9]..
