Gauge theory incorporating automatically confined fields

If quarks and gluons are truly unobservable in a direct manner, this should be an inevitable consequence of the theory describing them. A formalism, within which 'internal fields' are automatically 'confined', is developed by considering a class of transformations of quantum mechanical states that have no explicit macroscopic manifestation. One of the necessary consequences of this formalism is standard non-Abelian gauge theory, which arises in such a way that the results presented here seem to be consistent with accepted gauge-theoretic descriptions of subnuclear phenomena.

Quark-lepton symmetry and B − L as the U(1) generator of the electroweak symmetry group

We seek an interpretation of the U(1) part of the electroweak symmetry group in terms of the quantum number B − L. We show that the electroweak symmetry group, for which U(1) can be interpreted as a local B − L symmetry, is the left-right symmetry group SU(2) L × SU(2) R × U(1) L+R. The equating of U L+R(1) to U B− L (1) should lead to physical consequences which are not shared by standard gauge theory. B − L may also help to explain the inversion of quark and lepton mass spectra.

A calculation of the electron anapole moment

The static parity-violating coupling of the electron to an external electromagnetic field is calculated in the standard unified gauge theory of weak and electromagnetic interactions.

Measuring the P-odd asymmetry in electroproduction of the [formula omitted] resonance at low energies

We show that measurements of the P-odd asymmetry in the reaction e −+ N→ e −+δ( 2 2 , 3 2 at low energies might determine the combination α ∼ +(1.0–1.2γ β ∼ of the isovector phenomenological couplings, characterizing the parity nonconserving electron-quark neutral current interaction at presently accessible energies. They may provide also a very accurate determination of the parameter sin 2 θ W of the standard electroweak gauge theory.
