The TESLA Technical Design Report Part III: Physics at an e+e- Linear Collider
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.
This document is the final report of ATLAS-CMS Dark Matter Forum, a forum organized by ATLAS and CMS collaborations with participation experts on theories Matter, to select minimal basis set dark matter simplified models that should support design early LHC Run-2 searches. A prioritized, compact benchmark proposed, accompanied studies parameter space these repository generator implementations. also addresses how apply Effective Field Theory formalism for collider searches present results...
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 CMS detector team describes their experiment and observation of decay products from a standard model Higgs boson, allowing its mass to be determined.
A search for exotic unstable neutral and charged heavy leptons as well stable is performed with the L3 detector at LEP. Sequential, vector mirror natures of are considered. No evidence their existence found lower limits on masses set.
Single- and multi-photon events with missing energy are selected in 619/pb of data collected by the L3 detector at LEP centre-of-mass energies between 189GeV 209GeV. The cross sections process e^+e^- -> nu gamma (gamma) found to be agreement Standard Model expectations, number light neutrino species is determined, including lower data, N_nu = 2.98 +/- 0.05 0.04. Selection results also given form tables which can used test future models involving single- signatures LEP. These final states...
The absolute muon flux between 20 GeV and 3000 is measured with the L3 magnetic spectrometer for zenith angles ranging from 0 degree to 58 degree. Due large exposure of about 150 m2 sr d, excellent momentum resolution chambers, a precision 2.3 % at in vertical direction achieved. ratio positive negative muons studied 500 GeV, average charge found be 1.285 +- 0.003 (stat.) 0.019 (syst.).
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.
