Model for a light Z' boson.
A model of a light Z ′ boson is constructed and phenomenological bounds are derived. This Z ′ boson arises from a very simple extension to the Standard Model, and it is constrained to be light because the vacuum expectation values which generate its mass also break the electroweak gauge group. It is difficult to detect experimentally because it couples exclusively or primarily (depending on sym...
متن کاملHiggs Boson and Z Boson
The recent discovery of a Higgs boson at the LHC is a milestone in the quest to understand electroweak symmetry breaking. It is an important particle because it is responsible for the Higgs mechanism by which all particles acquire mass. The existence of a particle with zero spin suggests the need for new physics beyond the standard model. Z bosons are known to naturally exist in well-motivate...
متن کاملThe Z Boson
Precision measurements at the Z-boson resonance using electron{positron colliding beams began in 1989 at the SLC and at LEP. During 1989{95, the four CERN experiments made high-statistics studies of the Z. The availability of longitudinally polarized electron beams at the SLC since 1993 enabled a precision determination of the eeective electroweak mixing angle sin 2 W that is competitive with t...
متن کاملA Z ′ Boson and the Higgs Boson Mass
The Standard Model fit prefers values of the Higgs Boson mass mH that are below the 114 GeV direct lower limit from LEP II. The discrepancy is acute if the 3.2σ disagreement for sinθ` eff W from the two most precise measurements is attributed to underestimated systematic error. In that case the data suggests new physics to raise the predicted value of mH . One of the simplest possibilities is a...
متن کاملSelf-calibrating binary polarization analyzer.
We report a self-calibrating polarization analyzer fabricated with binary magneto-optic polarization rotators. The device automatically overcomes wavelength and temperature dependent inaccuracies and has impressive state of polarization and degree of polarization accuracies of 0.3 degrees and +/-0.5%, respectively, from 1460 to 1580 nm.
