A 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 کاملSearching for the intermediate-mass Higgs boson.
We study the feasibility of detecting a neutral Higgs boson Ho, with mass between 2mt w 80 GeV (by assumption) and 2mw at an e+e-machine or the SSC. Backgrounds to the production at an e+e-machine of Ho in association with a Z are calculated with particular emphasis on the case when mH M mz. We present a detailed survey of the signals for and backgrounds to the inclusive or associated productio...
متن کاملHiggs Boson Mass From Gauge-Higgs Unification
In certain five dimensional gauge theories the Standard Model Higgs doublet is identified, after compactification on the orbifold S/Z2, with the zero mode of the fifth component of the gauge field. An effective potential for the Higgs field is generated via quantum corrections, triggered by the breaking of the underlying gauge symmetry through boundary conditions. The quartic Higgs coupling can...
متن کاملMeasurement of the W boson mass.
We present a measurement of the W boson mass in W-->e(nu) decays using 1 fb-1 of data collected with the D0 detector during Run II of the Fermilab Tevatron collider. With a sample of 499830 W-->e(nu) candidate events, we measure M(W)=80.401+/-0.043 GeV. This is the most precise measurement from a single experiment.
متن کاملA More Precise Higgs Boson Mass
A great insight of twentieth-century science is that symmetries expressed in the laws of nature need not be manifest in the outcomes of those laws. Consider the snowflake. Its structure is a consequence of electromagnetic interactions, which are identical from any direction, but a snowflake only looks the same when rotated by multiples of 60◦ about a single axis. The full symmetry is hidden by ...
