PHYSICS WITH POLARIZED BEAMS IN e + e - COLLIDERS
The spin structure of the standard model of electroweak interactions is described, with emphasis on the relevance to polarized beam phenomena. The polarization dependence of the cross section, charge asymmetries, and examples of experimental measurements using longitudinal polarization are given. Longitudinal beam polarization is discussed in some detail, including electroweak radiative correct...
متن کاملPhysics Opportunities with Polarized e − and e + Beams at TESLA
Beam polarization at e+–e− linear colliders will be a powerful tool for high precision analyses. Often it is assumed that the full information from polarization effects is provided by polarization of the electron beam and no further information can be obtained by the simultaneous polarization of the positrons. In this paper we point out the advantages of polarizing both beams, and summarize the...
متن کاملPRECISION STANDARD MODEL TESTS WITH POLARIZED e+e− BEAMS*
The advent of polarized electron beams at the Stanford Linear Collider (SLC) makes possible the new precision electroweak tests now being performed by the SLC Large Detector (SLD) experiment. One such new technique, the left-right asymmetry measurement, allows remarkably direct measurement of the effective weak mixing angle, sin θ W = 0.2292± 0.0009(stat)± 0.0004(syst). When considered within t...
متن کاملQCD tests with polarized beams
We present three QCD studies performed by the SLD experiment at SLAC, utilizing the highly polarized SLC electron beam. We examined particle production differences in light quark and antiquark hemispheres, and observed more high momentum baryons and A’-% than antibaryons and Kt ’s in quark hemispheres, consistent with the “leading particle” hypothesis. We performed a search for jet handedness i...
متن کاملStudy of anomalous couplings at a 500 GeV e+e- linear collider with polarized beams.
We consider the possibility of observing deviations from the Standard Model gauge-boson self-couplings at a future 500 GeV e+e− linear collider. We concentrate on the case in which the electroweak symmetry breaking sector is strongly interacting and there are no new resonances within reach of the collider. We find a sensitivity to the anomalous couplings that is two orders of magnitude higher t...
