Scalar partner of $Z^0$-boson with larger mass value than $Z^0$-boson   mass in Subquark model
  The subquark model previously proposed by us showes that the intermediate $Z^0$-boson is realized as the composite object and its scalar partner has the mass value larger than $Z^0$-boson mass, which is about 110 GeV.
