Superconducting niobium cavity technology (used for ILC) makes it possible to build a linear collider with energy recovery (ERLC). To avoid parasitic collisions inside the linacs a twin LC is proposed. In this article, we consider the principle scheme of the collider and its energy consumption, and also estimate the achievable luminosity, which is limited by collision effects. With a duty cycle of 1/3, a luminosity of about $5times 10^{35} ,rm cm^{-2}s^{-1}$ is possible, which is almost two orders of magnitude higher than at the ILC, where the beams are used only once.
A strong candidate for the Standard Model Scalar boson, H(126), has been discovered by the Large Hadron Collider (LHC) experiments. In order to study this fundamental particle with unprecedented precision, and to perform precision tests of the closur
We present results from luminosity, energy and polarization studies at a future Linear Collider. We compare e+e- and e-e- modes of operation and consider both NLC and TESLA beam parameter specifications at a center-of-mass energy of 500 GeV. Realisti
A high luminosity energy recovery linac on ring type electron-positron collider operating as super charm factory is proposed. It is shown that the luminosity L=2.3 10^35 cm^-2s^-1 can be achieved for center of mass energy 3.77 GeV. The physics goals
A comprehensive review of physics at an e+e- Linear Collider in the energy range of sqrt{s}=92 GeV--3 TeV is presented in view of recent and expected LHC results, experiments from low energy as well as astroparticle physics.The report focuses in part
The relative center-of-mass energy spread at $e^+e^-$ colliders is about $10^{-3}$, which is much larger than the widths of narrow resonances produced in the s-channel in $e^+e^-$ collisions. This circumstance greatly lowers the resonance production
