Gauge-Boson Masses and Mixings in Left-Right---Symmetric Models
نویسنده
چکیده
The standard SU(2)t 8 U(l) gauge model' can accommodate all the present electroweak data. The recent discovery of the weak gauge bosons at CERN, with average masses M~= 80.9+ 2.0 GCV and Mz = 93.0+ 2.0 GCV, confirmed the validity of the standard model at low energies. These masses, in conjunction with the extrapolated and corrected value of the weak mixing angle, sin 0 = 0.217 + 0.014, and with the definition

Orbifold Breaking of Left-Right Gauge Symmetry
We study the five dimensional left-right symmetric gauge theory in which the gauge symmetry is broken down through orbifold compactification to four dimensions. The right handed charged gauge boson, WR is a Kaluza-Klein excited state in this model, and unlike the usual left-right symmetric model in four dimension, there is no mixing in the charged sector. We develop the formalism and give expre...

Low energy physics and left-right symmetry. Bounds on the model parameters. Abstract In any gauge model with spontaneous symmetry breakdown the gauge boson masses and their mixings are not independent quantities. They are interconnected through the vacuum expectation values (VEVs) of the Higgs sector. We discuss the low-energy experiments, namely electron-hadron, neutrino-hadron and neutrino-el...
متن کاملThe W' Searches
(IAS/Princeton). Any electrically charged gauge boson outside of the Standard Model is generically denoted W 0. A W 0 always couples to two diierent avors of fermions, similar to the W boson. In particular, if a W 0 couples quarks to leptons it is a leptoquark gauge boson. The most attractive candidate for W 0 is the W R gauge boson associated with the left-right symmetric models 1]. These mode...
متن کاملNeutrino masses and mixings
We propose a novel theoretical understanding of neutrino masses and mixings, which is attributed to the intrinsic vector-like feature of the regularized Standard Model at short distances. We try to explain the smallness of Dirac neutrino masses and the decoupling of the right-handed neutrino as a free particle. Neutrino masses and mixing angles are completely related to each other in the Schwin...
متن کاملConstraints on Extended Neutral Gauge Structures
Indirect precision data are used to constrain the masses of possible extra Z ′ bosons and their mixings with the ordinary Z. We study a variety of Z ′ bosons as they appear in E 6 and left-right unification models, the sequential Z boson, and the example of an additional U (1) in a concrete model from heterotic string theory. In all cases the mixings are severely constrained (sin θ < 0.01). The...
