Liquid argon (LAr) sampling calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. After detector consolidation during a long shutdown, Run-2 started in 2015 and about 150fb-1 of data at a center-of-mass energy of 13 TeV was recorded. Phase-I detector...

The ATLAS experiment is currently upgrading the first muon station in the high-rapidity region with the New Small Wheels (NSW), based on large-size multi-gap resistive strips Micromegas technology and small-strip Thin Gap Chambers (sTGC).

The NSW system is going to be installed in the ATLAS underground cavern during the LHC long shutdown 2 (2021) to enter in operation for Run3 (starting in... -

Being state-of-the-art, the Micro-Pattern Gaseous Detectors (MPGD) are widely accepted in several particle physics experiments like ATLAS, COMPASS, CMS, ALICE, CBM, EIC, ILC, etc. Micromegas is a type of MPGD which is famous for its simple single-stage amplification, high and stable gain, low ion feedback, and excellent spatial and temporal resolutions. It is a reliable candidate in many of...

The CMS experiment uses a two-level triggering system consisting of the Level-1, instrumented by custom-design hardware boards and delivering an output rate of 100 kHz, and the High Level Trigger, a streamlined version of the offline reconstruction software running on a computer farm, which sends a rate of about 1 kHz to permanent storage. This system has been evolving continuously since the...

The MUonE experiment aims at an independent and competitive determination of the leading hadronic contribution to the muon anomalous magnetic moment $a_\mu = (g_\mu-2)/2$, based on an alternative method, complementary to the existing ones. It could have a crucial role to clarify the comparison of the $a_\mu$ measurement with the Standard Model, given the recent Fermilab result, and the tension...

Antihydrogen experiments hosted at CERN's Antiproton Decelerator rely on charge exchange [1] or three body recombination [2] formation mechanisms. In both cases, the anti-atoms are produced in a wide range of highly excited Rydberg states preventing the atoms' extraction through Stark acceleration or magnetic focusing into a field-free environment and consequently hindering spectroscopy or...

We discuss here recent results on $e^+ e^−$ annihilation to hadrons below 2 GeV obtained with the SND detector at the VEPP-2000 collider. Among others we report cross sections and dynamics properties for the $e^+ e^- \to \pi^+ \pi^-$, $e^+ e^- \to n \bar{n}$, $e^+ e^- \to \eta \pi^0 \gamma$, and $e^+ e^- \to \eta \eta \gamma$ processes.

The CMS high granularity calorimeter (HGCAL) is a challenging detector that brings together tracking and calorimetry with silicon and scintillators, as well as meet the harsh radiation and pileup environment in the forward rapidity region during the High Luminosity LHC phase and exploit challenging signatures such as VBF/VBS production towards new physics searches. The HGCAL will be realised...

Due to their simplicity and comparatively low cost Resistive Plate Chambers are gaseous detectors widely used in high-energy and cosmic rays physics when large detection areas are needed. However, the best gaseous mixtures are currently based on tetrafluoroethane, which has the undesirable characteristic of a large Global Warming Potential (GWP) of about 1400 and, because of this, it is...

Experiments with antiprotons often require the tracking of the charged particles emerging from the annihilation process. The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration at the CERN Antiproton Decelerator (AD) has used several panels of scintillating bars placed around an interaction region to reveal the passage of charged pions and determine the...

The Monitored Drift Tube (MDT) provides precise tracking and momentum measurement in the ATLAS muon spectrometer. To accommodate higher event rates and provide better fake rejection in the High Luminosity LHC, a new integrated chamber with small-diameter MDT (sMDT) and thin Resistive Plate Chambers (tRPC) had been developed and will be installed into barrel inner layer of the muon detector for...

The ability to identify jets stemming from the hadronisation of b-quarks (b-jets) is crucial for the physics program of ATLAS.
Go to contribution page
The higher pileup conditions and the growing interest for measurements including c-jets and for searches in the high transverse momentum regime make the task more and more complex. The algorithms responsible for establishing the jet’s flavour are evolving quickly,... -

To meet new TDAQ buffering requirements and withstand the high expected radiation doses at the high-luminosity LHC, the ATLAS Liquid Argon Calorimeter readout electronics will be upgraded. Developments of low-power preamplifiers and shapers to meet low noise and excellent linearity requirements are ongoing in 130nm CMOS technology. In order to digitize the analogue signals on two gains after...

The instantaneous luminosity of the Large Hadron Collider at CERN will be increased by about a factor of five with respect to the design value by undergoing an extensive upgrade program over the coming decade. The largest phase-1 upgrade project for the ATLAS Muon System is the replacement of the present first station in the forward regions with the New Small Wheels (NSWs) during the long-LHC...

In order to provide optimal reconstruction of charged tracks, the positions of the nearly twenty-thousands silicon sensors of the central tracking system of the CMS detector must be determined at a better precision than their in- trinsic resolution, under a procedure called alignment. At CMS, the alignment also includes the orientation and surface deformations of the sensors. Data- driven...

L ~ 7.5 × 10$^{34}$ cm$^{-2}$s$^{-1}$ will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly...
