Neutral currents and Glashow-Iliopoulos-Maiani mechanism in SU(3)L

We study the Glashow-Iliopoulos-Maiani mechanism for flavor-changing neutral-current suppression in both the gauge and Higgs sectors, for models with SU(3)z, Igt U(1)iv gauge symmetry. The models di6'er from one another only with respect to the representation content. The main features of these models are that in order to cancel the triangle anomalies the number of families must be divisible by...

DESY 08-207 Collider constraints on interactions of dark energy with the Standard Model

We study models in which a light scalar dark energy particle couples to the gauge fields of the electroweak force, the photon, Z, and W± bosons. Our analysis applies to a large class of interacting dark energy models, including those in which the dark energy mass can be adjusted to evade fifth-force bounds by the so-called “chameleon” mechanism. We conclude that—with the usual choice of Higgs s...

Glashow-Weinberg-Salam Model: An Example of Electroweak Symmetry Breaking

In this essay, The generalization of the gauge theory for electromagnetic interaction of superconductivity to that for the weak interaction is discussed in detail , which is named as GlashowWeinberg-Salam Model. It turns out that the concept of symmetry spontaneous breaking plays an important role for the theory of eletroweak interaction. Consequencly, the broken symmetry SU(2)×U(1)Y → U(1)EM g...

Experiments with high-energy neutrino beams.

Experiments in which high-energy neutrinos were used as projectiles have made substantial contributions to our understanding of both weak and strong interactions, as well as the structure of hadrons. This article offers some illustrations. It recalls the discovery of the neutral weak current and some experiments on its nature. The sections on charged-current inclusive scattering recall the impo...
