Abstract
We study the characteristic features of a hypothetical candidate for new scalar field {chi}. The mass constraint under which such a {chi}-boson occurs is presented. The instability of weak vacuum is investigated. By considering the approximate breaking symmetry, we find that the mass m{sub {chi}} < 15 GeV of the {chi}-particle is unnatural. In the case of heavy enough top quark mass, m{sub top} {approx} 170 GeV (the recent CDF collaboration has reported m{sub top}{sup exp} = 174 {+-} 16 GeV), we have carried out that the physically acceptable {chi}-boson upper bound will not exceed the 1 TeV level. For certain values of m{sub top} and m{sub {chi}}, the one-loop approximation consideration leads to the fact that the physical (our) vacuum cannot be absolutely stable. 14 refs.
