Precision electroweak physics at LEP and the top-quark mass

Il Nuovo Cimento A, 1996
A status of precision measurements of electroweak observables at LEP is presented. The main improvements in 1995 are: final results from the 1993 lineshape scan and new preliminary results on the Z→b $$\bar b$$ partial width. All other measurements benefit from

Precision electroweak experiments and heavy physics: An update

Physical Review D, 1991
We update our previous global analysis of weak neutral current and {ital Z} and {ital W} data in which the parameters {ital h}{sub {ital V}} and {ital h}{sub {ital A}} associated with new heavy physics were constrained, by incorporating recent results on {ital Z} properties and {ital M}{sub {ital W}}.

Precision electroweak experiments and heavy physics: A global analysis

Physical Review Letters, 1990
The radiative corrections of heavy degenerate and nondegenerate electroweak multiplets do not decouple from low-energy experiments. Their effects can be parametrized in a general renormalization-scheme-independent way. For isospin-breaking ${\mathit{h}}_{\mathit{V}}$ and chiral-breaking ${\mathit{h}}_{\mathit{A}\mathit{Z}}$ and ${\mathit{h}}_{\mathit{A}

Electroweak Physics: Precision Studies

AIP Conference Proceedings, 2006
The utility of precision electroweak measurements for predicting the Standard Model Higgs mass via quantum loop effects is discussed. Current values of mW, sin2 θW(mZ)MS and mt imply a relatively light Higgs which is below the direct experimental bound but possibly consistent with Supersymmetry expectations.

Probing new physics with precise electroweak tests

AIP Conference Proceedings, 1992
Tests of the electroweak theory are becoming precise enough to shed light on new physics which contributes to radiative corrections. It is shown how the top quark and Higgs masses and other possible features of new physics are sensitive to each experiment and a framework is given for judging the potential impact of new tests.
