Implications of Precision Electroweak Measurements for Physics Beyond the SM
نویسنده
چکیده
Using the top quark and Z boson masses, mt andMZ , the QED coupling, , and the Fermi constant, GF , as input, other precision observables can be computed within the SM as functions of the Higgs boson mass,MH . For relatively low values of MH , the agreement with the measurements is found to be excellent, establishing the SM at the one-loop level. I will brie y review the constraints on MH and the experimental situation before moving beyond the SM. Besides the recent high precision measurements of the W boson mass [1,2], MW , the most important input into precision tests of electroweak theory continues to come from the Z factories LEP 1 [1] and SLC [3].

Precision Electroweak Measurements at Run 2 and Beyond
To chase out the elephants in the room, I recall that with the Higgs boson discovery the Standard Model (SM) is now complete, and with very few marginal exceptions it passed all the tests. Furthermore, the LHC did not yet find any convincing evidence for physics beyond the SM. Nevertheless, if nothing else does, at least dark matter provides a solid observational hint at the presence of new phy...
متن کاملThe Weak Charge of the Proton and New Physics
We address the physics implications of a precision determination of the weak charge of the proton, QW (p), from a parity violating elastic electron proton scattering experiment to be performed at the Jefferson Laboratory. We present the Standard Model (SM) expression for QW (p) including one-loop radiative corrections, and discuss in detail the theoretical uncertainties and missing higher order...
متن کاملPrecision determination of electroweak coupling from atomic parity violation and implications for particle physics.
We carry out high-precision calculation of parity violation in a cesium atom, reducing theoretical uncertainty by a factor of 2 compared to previous evaluations. We combine previous measurements with calculations and extract the weak charge of the 133Cs nucleus, QW=-73.16(29)expt(20)theor. The result is in agreement with the standard model (SM) of elementary particles. This is the most accurate...

متن کاملPrecision Electroweak Physics at Lep
Progress in precisionmeasurements of electroweak observables at LEP continues steadily. The highlights of 1993 are: a new scan of the Z line shape with precise beam energy determination by resonant depolarization, leading to a measurement of the Z width with 1:5 10 3 precision; rst results on absolute cross sections with high-precision luminosity monitors; high e ciency b-tagging with microvert...
