Precocious Gauge Symmetry Breaking in SU(6)× SU(2)R Model

In the SU(6)× SU(2)R string-inspired model, we evolve the couplings and the masses down from the string scale MS using the renormalization group equations and minimize the effective potential. This model has the flavor symmetry including the binary dihedral group D̃4. We show that the scalar mass squared of the gauge non-singlet matter field possibly goes negative slightly below the string scale...

Dynamical Symmetry Breaking in a Gauge Theory “ Thirring Model ” ∗

Dynamical fermion mass generation is studied in the three-dimensional Thirring model reformulated as a gauge theory by introducing hidden local symmetry. The analysis by use of Schwinger-Dyson equation is shown to exhibit a critical behavior as the number N of four-component fermions approaches Ncr = 128/3π 2. When we consider the models of massless self-interacting fermions, a central issue is...

Exploring residual gauge symmetry breaking

Simulations of pure-gauge SU(2) lattice gauge theory are performed in the minimal Coulomb gauge. This leaves a residual or remnant gauge symmetry still active which is global in three directions but still local in one. Using averaged fourth-dimension pointing links as a spin-like order parameter, the remnant symmetry appears to undergo spontaneous symmetry breaking at around β = 2.6. Both the B...

Symmetry-breaking model for X-chromosome inactivation.

In mammals, dosage compensation of X linked genes in female cells is achieved by inactivation of one of their two X chromosomes which is randomly chosen. The earliest steps in X-chromosome inactivation (XCI), namely, the mechanism whereby cells count their X chromosomes and choose between two equivalent X chromosomes, remain mysterious. Starting from the recent discovery of X chromosome colocal...

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...
