Spontaneous Symmetry Breaking in the SO(3) Gauge Theory to Discrete Subgroups

چکیده

In this paper we give a systematical description of the possible symmetry breakings in the SO(3)-gauge theory and show an algorithmical method to construct SU(2)or SO(3)-invariant Higgs potentials in an arbitrary irreducible representation using regular graphs. We close our paper with the explicit construction of the Lagrangian of the simplest SO(3)→ A4 theory. PACS 11.15.-q PACS 11.15.Ex

نظریه میدان ناجابه‌جایی و پارامترهای نقض لورنتس در QED

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...

Spontaneously Broken Su ( 5 ) Symmetries and One - Loop Effects in the Early Universe ∗

This paper studies one-loop effective potential and spontaneous-symmetrybreaking pattern for SU(5) gauge theory in De Sitter space-time. Curvature effects modify the flat-space effective potential by means of a very complicated special function previously derived in the literature. An algebraic technique already developed by the first author to study spontaneous symmetry breaking of SU(n) for r...

Gauge Symmetry Breaking in Gauge Theories—In Search of Clarification

The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle. Local gauge symmetry itself cannot break spontaneously in quantized gauge theories according to Elitzur’s theorem—even though the notion of a spontaneously broken local gauge symmetry is widely employed in textbook expositions of the Higgs mechanism, the standard account of mass gen...

Spontaneous symmetry breaking in the Higgs mechanism

The Higgs mechanism is very powerful: it furnishes a description of the electroweak theory in the Standard Model which has a convincing experimental verification. But although the Higgs mechanism had been applied successfully, the conceptual background is not clear. The Higgs mechanism is often presented as spontaneous breaking of a local gauge symmetry. But a local gauge symmetry is rooted in ...

Gauge Unification In Six Dimensions

We study the breaking of a supersymmetric SO(10) GUT in 6 dimensions by orbifold compactification. In 4 dimensions we obtain a N=1 supersymmetric theory with the standard model gauge group enlarged by an additional U(1) symmetry. The 4-dimensional gauge symmetry is obtained as intersection of the Pati-Salam and the Georgi-Glashow subgroups of SO(10), which appear as unbroken subgroups in the tw...
