Contact Interactions with Polarized Beams at HERA
The discovery potential of the HERA collider, with and without polarized beams, for electron-quark contact interactions in neutral current scattering is reviewed. The measurement of spin asymmetries in the polarized case could give crucial information on the chiral structure of new interactions.
متن کاملPlans for Polarized Beams at the Slc*
Precision tests of the electroweak interactions will soon be possible at the SLC and LEP. The SLC will be capable of providing longitudinal polarization of one incoming beam, the electrons, for such tests. Plans at the SLC to provide and monitor these beams are described, and some physics objectives are discussed. Invited talk presented at the Workshop on Tests of Electroweak Theories, Polarize...
متن کاملContact interaction probes at the Linear Collider with polarized electron and positron beams
For contact-interaction searches at the Linear Collider, we discuss the advantages of polarizing both the electron and the positron beams as compared with polarizing only the electron beam. In particular, for the processes ee → μμ, ττ, bb̄ and cc̄ at a future ee collider with √ s = 0.5 TeV we derive model-independent bounds on the four-fermion contact interaction parameters from studies of the he...
متن کاملPolarizing stored beams by interaction with polarized electrons.
A polarized, internal electron target gradually polarizes a proton beam in a storage ring. Here, we derive the spin-transfer cross section for e (p, p)e scattering. A recent measurement of the polarizing effect of a polarized atomic hydrogen target is explained when the effect of the atomic electrons is included. We also consider the interaction of a stored beam with a pure electron target whic...
متن کاملSearch for one large extra dimension with the DELPHI detector at LEP 2
Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are used to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of ∼ 650 pb −1 agree with the predictions of the Standard Model and allow a limi...
