The dynamical breaking of the supergauge symmetries in the massless supergauge Wess Zumino model isdiscussed without adding the Fayet-Iliopoulos term to the Lagrangian. It is shown, in terms of the Nambu-Jona-Lasiniomechanism, that the supersymmetry breaking and the gauge symmetry breaking can be realized dynamically. It is alsoshown that the dynamical breaking moves the vacuum expectation values of two scalar fields away from zero. In order torestore the symmetry of the vacuum, one of the two scalar fields is translated and at the same time the mass spectrumis changed too. 相似文献

The dynamical breaking of the supersymmetric Higgs model is discussed without adding the Fayet—Iliopoulos term to the Lagrangian. It is shown, in terms of the Nambu—Jona-Lasinio mechanism, that the supersymmetry breaking can be realized dynamically in the supersymmetric Higgs model. The supersymmetry behavior at finite temperatures is also investigated and it is shown that the supersymmetry broken dynamically at zero temperature can be restored at finite temperatures. 相似文献

In terms of the Nambu-Jona-Lasinio (NJL) mechanism, the dynamical symmetry breaking of a simple localgauge model is investigated. An important relation between the vacuum expectation value of gauge fields and scalarfields is derived by solving the Euler equation for the gauge fields. Based on this relation the SU(3) gauge potential isgiven which can be used to explain the asymptotic freedom and confinement of quarks in a hadron. The confinementbehavior at finite temperatures is also investigated and it is shown that color confinement at zero temperature can bemelted away under high temperatures. 相似文献

Generalized Yang-Mills theory has a covariant derivative which contains both vector and pseudoscalar gauge bosons. Based on this theory, we construct a U(4) strong interaction model. By using this U(4) generalized Yang-Mills model, we obtain that mesons can be realized as the colorless pseudoscalar gauge bosons. We also obtain a gauge potential solution which can be used to explain the asymptotic behavior and color confinement. 相似文献

Generalized Yang-Mills theory has a covariant derivative, which contains both vector and scalar gauge bosons. Based on this theory, we construct a strong interaction model by using the group U(4). By using this U(4) generalized Yang-Mills model, we also obtain a gauge potential solution, which can be used to explain the asymptotic behavior and color confinement. 相似文献

A maximally generalized Yang-Mills model, which contains, besides the vector part Vμ, also an axial-vector part
Aμ, a scalar part S, a
pseudoscalar part P, and a tensor part Tμν, is constructed and the
dynamical breaking of gauge symmetry in the model is also discussed. It is
shown, in terms of the Nambu-Jona-Lasinio mechanism, that the gauge symmetry breaking can be realized dynamically in the maximally generalized Yang-Mills
model. The combination of the maximally generalized Yang-Mills model and the
NJL mechanism provides a way to overcome the difficulties related to the Higgs field and the Higgs mechanism in the usual spontaneous symmetry breaking theory. 相似文献

The phase transition of a simple local gauge model is investigated in terms
of the Nambu-Jona-Lasinio mechanism and it is pointed out that the
physical vacuum of QCD is bound state of quark-antiquark pairs which can be
viewed, generally, as a nearly perfect color dia-electric medium. An
important relation between the vacuum expectation value of gauge fields and
scalar fields is also derived by solving the Euler equation for the gauge
fields. Based on this relation the
SUC(3) gauge potential is given which can be used to explain the asymptotic behavior and confinement of quarks in a hadron, and at the same time the Yukawa potential of strong interaction can be given too. 相似文献
