Looking Beyond the Standard Model through Precision Electroweak Physics
The most important hint of physics beyond the Standard Model (SM) from the 1995 precision electroweak data is that the most precisely measured quantities, the total, leptonic and hadronic decay widths of the Z and the effective weak mixing angle, sin θW , measured at LEP and SLC, and the quark-lepton universality of the weak charged currents measured at low energies, all agree with the predicti...
متن کاملPrecision Tests of the Standard Model
Recent published and preliminary precision electroweak measurements are reviewed, including new results on the mass of the top quark and mass and width of the W boson. The experimental results are compared with the predictions of the Standard Model and are used to constrain its free parameters, notably the mass of the Higgs boson. The agreement between measurements and expectations from theory ...
متن کاملPrecision Standard Model Measurements at the Tevatron
The CDF and DØ collaborations at the Tevatron have produced exquisite precision measurements on high-PT physics with their large datasets of pp̄ collisions. The top quark is being studied in great detail, and a precision of 1 1% in the measurement of its mass has been achieved. The large datasets of W and Z boson decays have allowed the most precise measurement of the W mass to date, and detaile...
متن کاملPrecision Standard Model Tests with Kaons
In kaon physics, several new precision measurements on flavour variables and CP violation have performed in the recent years. Presented are a new precise determination of the CKM parameter |Vus|, which combines the results of all experiments together with recent theoretical progress, and new measurements of the ratio RK = Γ(K + → eν)/Γ(K → μν), which is sensitive to contributions of a possible ...
متن کاملPrecision Electroweak Tests of the Standard Model
The present status of precision electroweak data is reviewed. These data include measurements of ee → ff , taken at the Z resonance at LEP, which are used to determine the mass and width of the Z boson. In addition, measurements have also been made of the forward-backward asymmetries for leptons and heavy quarks, and also the final state polarisation of the τ -lepton. At SLAC, where the electro...
