TL;DR: In this article, it was shown that the classical dynamics of several slowly moving monopoles corresponds to a geodesic motion in the manifold of exact, static multi-monopole configurations.

TL;DR: In this paper, the authors show that the U(1) theory possesses only short-range couplings, and hence the finite-temperature confinement phase transition (when continuous) is accompanied by long-range fluctuations only in the order parameter.

TL;DR: In this paper, a new pattern of symmetry breaking for SO(10) grand unified models was discussed, in which SO (10) breaks to SU(5)' ×U(1) and then further breaks to SO(3) C ×SU(2) L ×U (1) at lower scale.

TL;DR: In this article, a scenario for grand unified models based on local supersymmetry was proposed, where the gravitino mass induces mass splittings in the low energy theory and allows us to understand a hierarchy of M p = 10 19 GeV to M w = 10 2 GeV naturally.

TL;DR: In this article, the Weinberg-Salam theory is reviewed emphasizing its aspects of a renormalizable gauge field theory with spontaneous symmetry breaking, where all the renormalization constants are fixed on the mass shell of gauge bosons, fermions and Higgs bosons.
Abstract: The electroweak theory (the Weinberg-Salam theory) is reviewed emphasizing its aspects of a renormalizable gauge field theory with spontaneous symmetry breaking. The on-shell renormalization procedure is developed where all the renormalization constants are fixed on the mass shell of gauge bosons, fermions and Higgs bosons. It is applied to the calculation of radiative corrections to leptonic processes ν_µe → ν_µe, ν_µe → ν_µe, ν_µe → µν_e and µ → e ν_e ν_µ. The experimental significance of the radiative corrections and the effect of the corrections to the values of physical masses of W^± and Z are discussed. The relation among different renormalization procedures is clarified.

TL;DR: In this article, the spontaneous breaking of the gauge group in supersymmetric Yang-Mills theories with unbroken supersymmetry was studied and a group-theoretical analysis was given.
TL;DR: In this article, it was shown that for a U(1) gauge theory with a Fayet-Illiopoulos term to consistently coupled to supergravity, preserving gauge invariance, the superpotential must be R invariant.
TL;DR: In this paper, it was shown that if the phase transition is strongly of first order, such gauge theories combined with general relativity yield a surprising prediction; although the Creator might have made a unitary universe, many mini-universe are produced sequentially afterward as a result of the phase-transition.
TL;DR: In this paper, some observable effects of the possible sub-structure of leptons and quarks are discussed in subquark models of lepton and quark, including possible deviations of anomalous magnetic moments from the QEWD (and QCD) predictions.
TL;DR: In this article, a supersymmetric model for SU(5) was proposed, in which SU (5) → SU (3) × SU (2) × U (1) and SU(3)×U (1)/U (2)/U(1) was constructed by using Witten's method for producing a large gauge hierarchy.

TL;DR: In this article, various gauge fields are coupled to the free Dirac equation according to symmetry principles, and the vacuum stability of the Dirac field is studied for the cases of external electromagnetic (U(1)), gravitational (Poincare group including torsion) and Yang-Mills (SU(2)) potentials.
TL;DR: In this article, a reduced model for the U(∞) gauge theory is constructed in a translation invariant gauge, where the rule is U(x, x+μ)→Dk(x)VμDk+(x) where Vμ belongs to the coset U(N)U(1)N and Dk(X) is a diagonal plane-wave matrix representing translations.

TL;DR: In this article, a purely fermionic action with gauge and general relativistic invariances is proposed, which implies a unified treatment of gravity and gauge theories without elementary metric tensor and gauge boson fields.
TL;DR: In this paper, a solution to the gauge hierarchy problem in theories with softly broken supersymmetry is proposed, which can resuscitate classically sick theories, producing the large scale from the small supersymmetric breaking scale.
TL;DR: In this article, the lepton-flavour nonconservation in the left-right symmetric gauge theory with both Majorana and Dirac mass terms of neutrinos is studied.
Abstract: The lepton-flavour nonconservation is studied in the left-right symmetric gauge theory with both Majorana and Dirac mass terms of neutrinos. The tree graphs with physical Higgs scalar exchange and the one-loop graphs with light (left-handed) and heavy (right-handed) gauge boson exchange contributing to /1~ er and /1~ eee are evaluated. The one-loop graphs with intermediate heavy Majorana neutrinos are shown to give more important effects than those with light Majorana neutrinos. The latter contributions to the rare decay rates are negligibly small, independently of the value of 7J == M~jM~R' because of the strong suppression by powers of light neutrino masses mvL. The former contributions are not directly related to mvL but depend on 7J. They can lead to relatively large values of the rare decay rates, unless 7J is inhibitingly small. The predictions for the rates of lepton-flavour changing processes /1~ er, /1~eee, Z~/1e, /1N~eN, KL~/1e and K+~J[+/1e- in the present gauge model are com pared with similar predictions in other types of gauge models with different types of neutrino masses.

TL;DR: In this paper, the exact mass-dependent one-loop two-point functions involving the photon and Z field in any linear ξ-gauge were derived and the special gauge a = ξ −1 = −3 was shown to play a peculiar role.
TL;DR: In this paper, the structure of the charged leptonic weak currents is studied in the framework of two models, the fermion-mirror fermions mixing model connected with many grand unification schemes, and the left-right symmetric SU(2) L × SU (2) R × U(1) flavor model.

TL;DR: If Z 0 and W ± gauge bosons are composite objects, several multiphoton and multigluon Z 0 decay modes can become well observable and can be used to test the nature of the subconstituents as mentioned in this paper.
TL;DR: The possible occurrence of large Majorana masses for right-handed neutrinos vitiates previous limits on the mixing between left-and right-hand gauge bosons in symmetrical models of weak interactions as mentioned in this paper.
