Challenge of polarized beams at future colliders
A short overview about the potential of polarized beams at future colliders is given. In particular the baseline design for polarized beams at the ILC is presented and the physics case for polarized e and e is discussed. In order to fulfil the precision requirements spin tracking from the source to the interaction point is needed. Updates concerning the theoretical calculations as well as their...
متن کاملContact 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 کاملCHARGINO PAIR PRODUCTION AT ee COLLIDERS WITH POLARIZED BEAMS
The chargino χ̃±1,2 system can be reconstructed completely in e +e− collisions. By measuring the total cross sections and the asymmetries with polarized beams in e+e− → χ̃i χ̃−j [i, j = 1, 2], the chargino masses and the gaugino–higgsino mixing angles of these states can be determined very accurately. If only the lightest charginos χ̃±1 are kinematically accessible, transverse beam polarization is ...
متن کاملPolarized electron beams for linear colliders*
Longitudinally polarized electron beams for high energy collisions provide a sensitive way to explore the electroweak process as well as an effective means to measure spin dependent properties of particles. Once created, such beams are readily accelerated by linacs without loss of polarization, although emittance damping rings present potential hazards. The essential elements of a collider nece...
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...
