Assumption of nonvanishingness of vacuum expectation of the scalar field for spontaneous symmetry breaking is superfluous

چکیده
For spontaneous breaking of global or gauge symmetry, it is superfluous to assume that the vacuum expectation value of the scalar field manifesting the symmetry is nonvanishing. The vacuum with spontaneous symmetry breaking simply corresponds to the nonzero number of particles of one or more components of the real scalar field.

For spontaneous breaking of global or gauge symmetry, it is superfluous to assume that the vacuum expectation value of the scalar field manifesting the symmetry is nonvanishing. PACS Numbers: 11.30.Qc Electronic address: [email protected] 1 A crucial ingredient of the theories of spontaneous symmetry breaking is the assumption that the vaccum expectation value of the scalar field manifest...
متن کاملInflation From Symmetry Breaking Below the Planck Scale
We investigate general scalar field potentials V (φ) for inflationary cosmology arising from spontaneous symmetry breaking. We find that potentials which are dominated by terms of order φm with m > 2 can satisfy observational constraints at an arbitrary symmetry breaking scale. Of particular interest, the spectral index of density fluctuations is shown to be independent of the specific form of ...
متن کاملNotes on the spontaneous breaking of SU(N) and SO(N) via a second-rank tensor multiplet
The group theory of the spontaneous breaking of SU(N) is explored. Two specific cases are analyzed in detail: (i) SU(N) is broken to SO(N) via a scalar field vacuum expectation value for a second-rank symmetric tensor multiplet, and (ii) SU(2N) or SU(2N +1) is broken to Sp(2N) via a scalar field vacuum expectation value for a secondrank antisymmetric tensor multiplet. The case of the spontaneou...
متن کاملU A ( 1 ) Symmetry Breaking and the Scalar Sector of QCD
It is shown that most of the unusual properties of the lowest lying scalar (and pseudoscalar) mesons can be understood, at the qualitative and quantitative level, on the basis of the breakdown of the UA(1) symmetry coupled to the vacuum expectation values of scalars by the spontaneous breaking of chiral symmetry.
متن کاملDynamically Induced Spontaneous Symmetry Breaking in 3-3-1 Models
We show that in SU(3)C ⊗ SU(3)L ⊗ U(1)N (3-3-1) models embedded with a singlet scalar playing the role of the axion, after imposing scale invariance, dynamical symmetry breaking of Peccei-Quinn symmetry occurs through the one-loop effective potential for the singlet field. We, then, analyze the structure of spontaneous symmetry breaking by studying the new scalar potential for the model, and ve...
