This note presents constraints on Standard Model parameters using published and preliminary precision electroweak results measured at the electron-positron colliders LEP and SLC. The results are compared with precise electroweak measurements from other experiments, notably CDF and D{\O}at the Tevatron. Constraints on the input parameters of the Standard Model are derived from the results obtained in high-$Q^2$ interactions, and used to predict results in low-$Q^2$ experiments, such as atomic parity violation, M{\o}ller scattering, and neutrino-nucleon scattering.

Original abstract

This note presents constraints on Standard Model parameters using published and preliminary precision electroweak results measured at the electron-positron colliders LEP and SLC. The results are compared with precise electroweak measurements from other experiments, notably CDF and D{\O}at the Tevatron.

Hadronic Z- and tau-Decays in Order alpha_s^4
hep-ph 2008-01 accept novelty 8.0 of 10

A five-loop QCD calculation of the alpha_s^4 correction to hadronic R ratios yields alpha_s(M_Z) = 0.1198 +/- 0.0015, with Z- and tau-derived values now in close agreement.
Complete QCD Corrections to Hadronic $Z$--Decays in Order $\alpha_s^4$
hep-ph 2012-01 conditional novelty 7.0 of 10

The last missing O(alpha_s^4) piece of the hadronic Z decay rate, the axial singlet contribution, is computed in the heavy-top limit, completing the fourth-order QCD prediction.
Fitting the Phenomenological MSSM
hep-ph 2009-04 conditional novelty 6.0 of 10

A 25-parameter global Bayesian fit of the pMSSM finds that the lightest CP-even Higgs mass and the stop masses are approximately prior independent, while most sparticle masses and all dark matter properties are not.
The muon $g$-2 and $\Delta \alpha$ connection
hep-ph 2020-06 accept novelty 5.0 of 10

Adjusting hadronic cross-section data to erase the muon g-2 discrepancy is excluded above roughly 0.7 GeV at 95% CL by the global electroweak fit, and requires implausibly large cross-section increases below that energy.
Measuring the Higgs Sector
hep-ph 2009-04 conditional novelty 5.0 of 10

With 30 inverse femtobarns at the LHC, Higgs couplings to gauge bosons and fermions can be extracted to roughly 20 to 40 percent, provided the bottom Yukawa is measured via a WH/ZH subjet analysis.

Revisiting the Global Electroweak Fit of the Standard Model and Beyond with Gfitter
hep-ph 2008-11 accept novelty 5.0 of 10

Combining electroweak precision data with direct Higgs searches gives M_H = 116.4 +18.3/-1.3 GeV and alpha_S(M_Z) = 0.1193 +0.0028/-0.0027, and excludes a charged Higgs below 240 GeV in the Type-II 2HDM.

A 2008 review of what the LHC was expected to teach about top quarks: their decay, pair production, single production, spin effects, and possible new physics.

How later papers used it

54 later papers cite it

Evidence: substantial. 53 of the citing papers share no author with it, and 24 of those carry a confident label from Pith's citation classifier.

Pith read 33 of the 75 citing sentences, choosing only those whose citation markers point at this paper alone, and wrote the paraphrases from them. The summary, the counts, the evidence level, the links and the quotes come from code; the summary counts the papers listed below. A later paper is listed under a label when Pith's citation classifier gives one of its sentences that label at probability 0.8 or more (0.95 for support), Pith's reading finds that the citing paper itself did it, and a second check confirms the paraphrase against the sentence. This section lists uses only. It does not list criticism or disagreement, so their absence here says nothing about how the paper has been received. Papers that share an author with this one are listed apart, under "By the same authors". A quote is the citing authors' own sentence, shown when their paper's licence is CC BY, CC BY-SA or CC0. JSON
