Many physics analyses using the Compact Muon Solenoid (CMS) detector at the LHC require accurate, high resolution electron and photon energy measurements. Excellent energy resolution is crucial for studies of Higgs boson decays with electromagnetic particles in the final state, as well as searches for very high mass resonances decaying to energetic photons or electrons. The CMS electromagnetic...

The ATLAS Tile Calorimeter (TileCal), as a substantial part of the hadronic calorimeter system of the ATLAS detector, records energy deposits and jointly with other calorimeters reconstructs hadrons, jets, tau-particles and missing transverse energy. It also assists in muon identification. The TileCal is the hadronic sampling calorimeter, which is constructed out of alternating iron absorber...

The Tile Calorimeter (TileCal) is the central section of hadronic calorimeter of the ATLAS experiment at the LHC. This sampling device uses steel plates as absorber and scintillating tiles as active medium and its response is calibrated to electromagnetic scale by means of several dedicated calibration systems.

Luminosity measurements in ATLAS are provided primarily by LUCID detector, but rely on other detectors for determining the systematics associated with this measurement. The Tile Calorimeter, the central hadronic calorimeter at the ATLAS experiment, plays an especially important role because the Tile luminosity measurement is independent of pileup, a feature shared with the Track counting...

The precise measurement of the luminosity is one of the key requirements for every ATLAS analysis at the Large Hadron Collider (LHC) at CERN. Particularly in high precision experiments, the uncertainty on the luminosity can be one of the main limitations. Therefore, its reduction is the prime goal of the ATLAS luminosity program, requiring a precise understanding of the contributing factors....

During Run 2, LHC delivered instantaneous luminosities of $\approx 10^{34}$ cm$^{-2}$ s$^{-1}$ at $\sqrt{s}=13\; {\rm TeV}$. This permitted monitoring of the luminosity over a time granularity as short as $60\;{\rm s}$, using the counts of $Z\rightarrow \ell \ell$ events reconstructed by selecting two, well-idenfitied high $p_T$ electrons or muons in the invariant mass range of $66 < m_{\ell...

Cosmic muon data accumulated by the NOvA neutrino detector, located 100m underground at Fermilab, allows for study of geological and man-made structures directly contributing to the overburden of the detector. We present results of a muon radiographic analysis of the cosmic ray data, obtained without subtracting the surface muon flux (free sky data). Instead, we use the internal geometrical...

The Compact Muon Solenoid (CMS) detector is one of the main experiments of the Large Hadron Collider (LHC). Many aspects of its broad physics program rely on our ability to trigger, reconstruct and identify events with muons in a wide range of momenta, from a few GeV to the TeV scale. We study the performance of muon identification and isolation in CMS in pp collision data at 13 TeV recorded...

The upgrade of the Large Hadron Collider (LHC) to the High Luminosity LHC (HL-LHC) is required to probe the physics beyond Standard Model. After the ongoing long shutdown (LS2) and eventually after LS3 in 2026, the accelerator luminosity will be increased up to 7 times as compared to designed luminosity value i.e. 1034 cm-2s-1. To meet the requirements of higher rates environment of HL-LHC...

The ATLAS experiment aims to record about 1 kHz of physics collisions. This is achieved by using a two-level trigger system to select interesting physics events while reducing the data rate from the 40 MHz LHC crossing frequency. Events are selected based on physics signatures such as the presence of energetic leptons, photons, jets or large missing energy. The wide physics programme carried...

Many analyses in ATLAS rely on the identification of jets containing b-hadrons (b-jets) at high efficiency while rejecting more than 99% of non-b-jets. Identification algorithms, called b-taggers, exploit b-hadron properties such as their long lifetime, their high mass, and high decay multiplicity to achieve this. Recently developed ATLAS b-taggers using neural networks are expected to...
