The TESLA Technical Design Report Part III: Physics at an e+e- Linear Collider

10.48550/arxiv.hep-ph/0106315 preprint EN other-oa arXiv (Cornell University) 2001-01-01

A measurement of the cosmic ray positron fraction e+/(e++e−) in energy range 1–30 GeV is presented. The based on data taken by AMS-01 experiment during its 10 day Space Shuttle flight June 1998. proton background suppression order 106 reached identifying converted bremsstrahlung photons emitted from positrons.

The design and construction of the silicon strip microvertex detector (SMD) L3 experiment at LEP are described. We present sensors, readout electronics, data acquisition system, mechanical assembly support, displacement monitoring systems radiation system recently installed double-sided, double-layered SMD. This utilizes novel sophisticated techniques for its readout.

The 2011 Les Houches workshop was the first to confront LHC data. In two years since previous there have been significant advances in both soft and hard QCD, particularly areas of multi-leg NLO calculations, inclusion those calculations into parton shower Monte Carlos, tuning non-perturbative parameters Carlos. These proceedings describe theoretical that taken place, impact early data, for future development.

Scalar partners of quarks and leptons, predicted in supersymmetric models, are searched for e^+e^- collisions at centre-of-mass energies between 192GeV 209GeV LEP. No evidence any such particle is found a data sample 450 pb^-1. Upper limits on their production cross sections set lower masses derived the framework Minimal Supersymmetric Standard Model.
