ELECTROWEAK RESULTS FROM NUTEVNuTeV
نویسنده
چکیده
We report our measurement of the weak mixing angle, sin 2 W , in neutrino{nucleon deep inelastic scattering in the NuTeV experiment at Fermilab. Using separate neutrino and anti-neutrino beams we are able to use the Paschos-Wolfenstein relations to extract sin 2 W with low systematic errors. Our preliminary result is sin 2 W (on?shell) 1 ? m 2 W =m 2 Z = 0:22530:0019(stat)0:0010(syst), which in the Standard Model is equivalent to a W mass measurement of 80:260:11 GeV/c 2 .

Effective Hamiltonian of Electroweak Penguin for Hadronic b Quark Decays
In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. The gluonic penguin structure of hadronic decays is studied thro...

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...

The measurements of electroweak sector of the Standard Model are presented, including most recent results from LEP, Tevatron and HERA colliders. The robustness of the Standard Model is illustrated with the precision measurements, the electroweak fits and the comparisons to the results obtained from low energy experiments. The status of the measurements of the W boson properties and rare product...
متن کاملFor Electroweak Corrections ?
The Born approximation, based on ¯ α ≡ α(m Z) instead of α, reproduces all electroweak precision measurements within their (1σ) accuracy. The low upper limits for the genuinely electroweak corrections constitute one of the major achievements of LEP. The astonishing smallness of these corrections results from the cancellation of a large positive contribution from the heavy top quark and large ne...
متن کاملElectroweak and Qcd Results from Dø for the Dø Collaboration
We present some of the results in the areas of QCD and Electroweak physics for Run II of the DØ experiment at the Fermilab Tevatron. QCD results include dijet angular decorrelations and inclusive jet and dijet cross sections. Electroweak results include the decay of Z bosons to tau pairs and several results on gauge boson pairs. No deviations from the Standard Model have been observed.
