Higgs 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 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 کاملMeasuring the Higgs boson mass in dileptonic W -boson decays at hadron colliders
It is expected that hadron collider measurements of the Higgs boson mass using the decay h → W+W−, followed by the leptonic decay of each W -boson, will be performed by fitting the shape of a distribution that is sensitive to the Higgs mass. We demonstrate that the variable most commonly used to measure the Higgs mass in this channel is not optimal as it contains an unnecessary and even counter...
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 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 ...
