The proposed International Linear Collider (ILC) is well-suited for discovering physics beyond the Standard Model and for precisely unraveling the structure of the underlying physics. The physics return can be maximized by the use of polarized beams. This report shows the paramount role of polarized beams and summarizes the benefits obtained from polarizing(More)
We discuss four-fermion contact-interaction searches in the processes e + e − → µ + µ − , c¯ c and b ¯ b at a future e + e − Linear Collider with c.m. energy √ s = 0.5 TeV and with both beams longitudinally polarized. Our analysis is based on the measurements of familiar polarized observables such as the total cross section and the(More)
We discuss contact-interaction searches in the processes e + e − → µ + µ − , b ¯ b and c¯ c at an e + e − Linear Collider with c.m. energy √ s = 0.5 TeV and with longitudinally polarized beams. The measurement of polarized cross sections allows to study the individual helicity cross sections, and consequently to derive separate, model-independent,(More)
We derive model-independent constraints on four-fermion contact interaction-type dynamics from the published preliminary LEP2 experimental data on e + e − annihilation into µ + µ − and τ + τ − pairs measured at different energies between 130 and 207 GeV. The basic observables are chosen to be the total cross section and the forward-backward asymmetry , and(More)
