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...
Simplified Template Cross Sections (STXS) have been adopted by the LHC experiments as a common framework for Higgs measurements. Their purpose is to reduce theoretical uncertainties that are directly folded into measurements much possible, while at same time allowing combination of between different decay channels well experiments. We report complete, revised definition STXS kinematic bins (stage 1.1), which be used upcoming ATLAS and CMS using full Run 2 datasets. The main focus on three...
The increase of the particle flux at HL-LHC with instantaneous luminosities up to L=7.5 × 10 34 cm −2 s −1 will have a severe impact on ATLAS detector reconstruction and trigger performance. end-cap forward region where liquid Argon calorimeter has coarser granularity inner tracker poorer momentum resolution be particularly affected. A High Granularity Timing Detector installed in front calorimeters help charged-particle luminosity measurement. This low angle is introduced augment new...
The ATLAS liquid Argon electromagnetic calorimeter provides multiply-sampled digitised signals with a frequency of 40 MHz. signal amplitude is reconstructed from the samples using digital filtering technique; computation filter weights requires precise knowledge shape emerging front-end electronics. Each read-out channel can be calibrated by means electronic pulsers that mimic ionisation produced an shower. However, calibration differs one, because injected current pulses are different in...
In 2004 at the ATLAS (A Toroidal LHC ApparatuS) combined test beam, one slice of barrel detector (including an Inner Detector set-up and Liquid Argon calorimeter) was exposed to particles from H8 SPS beam line CERN. It first occasion electron performance ATLAS. This paper presents results obtained for momentum measurement p with LAr calorimeter (energy E linearity resolution) in presence a magnetic field momenta ranging 20 GeV/c 100 GeV/c. Furthermore particle identification capabilities...
The reconstruction of photons in the ATLAS detector is studied with data taken during 2004 Combined Test Beam, where a full slice was exposed to beams particles known energy at CERN SPS. results presented show significant differences longitudinal development electromagnetic shower between converted and unconverted as well total measured energy. potential use reconstructed means precisely map material tracker front calorimeter also considered. All obtained are compared detailed Monte-Carlo...
Smart and precision agriculture concepts require that the farmer measures all relevant variables in a continuous way processes this information order to build better prescription maps predict crop yield. These feed machinery with variable rate technology apply correct amount of products right time place, improve farm profitability. One most estimate yield is Leaf Area Index. Traditionally, index can be obtained from manual measurements or aerial imagery: former consuming latter requires use...
The search strategy for the Standard Model Higgs boson at Large Hadron Collider is reviewed, with a particular emphasis on its potential observation by ATLAS and CMS detectors in $γγ$, $τ^+τ^-$, $ZZ^{*}$ $WW^{*}$ final states. combined discovery of discussed, as well expected exclusion limits production rate times branching ratio function mass collected luminosity.
The ATLAS Liquid Argon electromagnetic calorimeter uses a digital filtering technique to reconstruct the signal amplitude from ionization pulse samplings; coefficients computation requires knowledge of profile in each cell. This waveform must have correct normalization with respect calibration used compute actual electronic gain channel, thus taking into account differences between two waveforms, as well and different current paths detector. A stand-alone algorithm is developed predict for...
A new method for calibrating the hadron response of a segmented calorimeter is developed and successfully applied to beam test data. It based on principal component analysis energy deposits in layers, exploiting longitudinal shower development information improve measured resolution. Corrections invisible hadronic lost dead material front between calorimeters ATLAS experiment were calculated with simulated Geant4 Monte Carlo events used reconstruct pions impinging during 2004 Barrel Combined...
