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 readout electronics of the ATLAS Liquid Argon (LAr) Calorimeter (for phase II high luminosity Large Hadron Collider at CERN) will be replaced and integrated in a single chip order to reduce power dissipation by an magnitude provide fully digital data. cornerstone circuit is preamplifier which very demanding terms low noise, large dynamic range (at least 16 bits) precise input impedance (25 or 50 Ohms) terminate cables from detector. An innovative architecture proposed fulfill these...
Abstract ALFE2 is an ATLAS Liquid Argon Calorimeter (LAr) Front-End ASIC designed for the HL-LHC upgrade. comprises four channels of pre-amplifiers and CR-(RC) 2 shapers with adjustable input impedance. features two separate gain outputs to provide 16-bit dynamic-range coverage optimum resolution. characterized using a Test Board (FETB) based on Zynq UltraScale+ MPSoC octal-channel high-speed ADCs. The test results indicate that fulfills or greatly exceeds all specifications gain, noise,...
Noble liquid calorimeters have been successfully used in particle physics experiments for decades. The project presented this article is that of a new noble calorimeter concept, where novel design allows us to fulfil the stringent requirements on calorimetry programme electron-positron Future Circular Collider at CERN. High granularity achieved through specific readout electrodes and high-density cryostat feedthroughs. Excellent performance can be reached very light low electronics noise....
Après deux ans d’arrêt technique, le grand collisionneur de hadrons du CERN a repris ses opérations en 2015, à une énergie et intensité bien plus élevées. Les détecteurs géants ATLAS CMS ont été adaptés ce nouvel environnement, par l’amélioration leurs systèmes détection leur capacité sélectionner temps réel les collisions intéressantes.L’analyse des données collectées jusqu’à l’été 2016 déjà fourni résultats très attendus, sur la compréhension boson Higgs recherche d’une nouvelle physique...

Six years after the first observation of Higgs boson, exploration sector Standard Model lagrangian remains at full swing. Analysing up to $80\,\mathrm{fb}^{-1}$ $13\,$TeV collision data recorded during Run-2 LHC, ATLAS collaboration has produced a number measurements on boson in all its main production modes and many decay channels. These analyses are combined measure differential distributions or extract information couplings boson. This turns allows test predictions terms couplings, set...
The analog front-end readout electronics of the ATLAS Liquid Argon (LAr) Calorimeter will be replaced by a single chip for phase II high luminosity Large Hadron Collider at CERN. cornerstone circuit is preamplifier which very demanding in terms low noise (0.4 nV/√Hz), large dynamic range (up to 10 mA, 16 bits) and precise input impedance (25 or 50 Ohms) terminate cables from detector. LAUROC1 ASIC integrates an innovative architecture fulfil these requirements. Detailed measurements are presented.
The framework of Effective Field Theory (EFT) Lagrangians is an effective and systematic way to search for physics beyond the Standard Model at LHC using distributions events in many topologies. A large number measurements performed by ATLAS CMS experiments top-quark, Higgs electroweak sectors include EFT interpretations. They provide complementary constraints, although with various choices bases interpretation frameworks. No significant deviations from predictions have been observed so far.
