The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV measured properties compatible those Standard-Model Higgs boson, coupled absence discoveries phenomena beyond Standard Model at TeV scale, has triggered interest in ideas for future factories. A circular e+e- collider hosted 80 to 100 km tunnel, TLEP, is among most attractive solutions proposed so far. It clean experimental environment, produces high luminosity top-quark, W Z studies, accommodates multiple...
This document a outlines set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these have when applied searches at LHC, provide number useful expressions reference. The list includes both s-channel t-channel scenarios. For s-channel, spin-0 spin-1 mediations are discussed, also realizations where Higgs particle provides portal between visible sectors. guiding principles underpinning proposed...
On July 4, 2012, the discovery of a new boson, with mass around 125 GeV/c2 and properties compatible those standard-model Higgs was announced at CERN. In this context, high-luminosity electron-positron collider ring, operating in LHC tunnel centre-of-mass energy 240 GeV called LEP3, becomes an attractive opportunity both from financial scientific point views. The performance suitability CMS detector are evaluated, emphasis on accurate measurement boson properties. precision expected for...
The CMS Electromagnetic crystal Calorimeter (ECAL) must be precisely inter-calibrated if its full potential performance is to realized.In this note, a detailed Monte Carlo study of in-situ intercalibration the ECAL crystals using isolated electrons described.The achievable precision depends on quality and number available per crystal.This in turn upon position corresponding thickness material front ECAL.
The CMS CERN Analysis Facility (CAF) was primarily designed to host a large variety of latency-critical workflows. These break down into alignment and calibration, detector commissioning diagnosis, high-interest physics analysis requiring fast-turnaround. In addition the low latency requirement on batch farm, another mandatory condition is efficient access RAW data stored at Tier-0 facility. CAF also foresees resources for interactive login by number collaborators located CERN, as an entry...
The four LEP experiments ALEPH, DELPHI, L3 and OPAL successfully recorded e+e- collision data during the years 1989 to 2000. As part of ordinary evolution in High Energy Physics, these can not be repeated their is therefore unique. This article briefly reviews preservation efforts undertaken by beyond end taking. current status preserved associated tools summarised.
The measurements of W-pair cross sections performed by the L3 experiment at LEP collider are herein reported. statistics collected in period 1996-2000 amounts to more than 8000 events distributed over a large center-of-mass energy range: 161–208 GeV. From section measurements, also W branching fractions leptons and hadrons derived with percent precision: BR ( → qq) = 68.47 ± 0.49 0.33% ℓν) 10.51 0.16 0.11%. improving statistical accuracy is now approaching systematic uncertainties.

The reaction e + -→ -γ * γ → -hadrons for quasi-real photons is studied at LEP using data from √ s = 130 GeV up to 202 GeV.Results on the total cross sections σ(e -hadrons) and σ(γγ hadrons) are obtained two-photon centre-of-mass energies ranging in 5 ≤ W γγ 185 GeV.A steeper rise with twophoton energy as compared hadron-hadron photon-proton observed.Several theoretical models have also been tested.
