The MEG experiment has set the world’s most stringent limit of 4.2 $\times$ 10$^{-13}$ (90% C.L.) on the branching ratio of the charged lepton flavour violating decay mu+->e+ gamma at the Swiss intense continuous surface muon beam facility, the Paul Scherrer Institute. After an intense upgrade program, the MEG-II experiment started data taking in 2021. To achieve an order of magnitude...
An imaging calorimeter prototype for the new generation of satellite experiments sensitive to sub-GeV photons is proposed. The detector is composed of a thin scintillator crystal of LYSO coupled with two crossed planes of wavelength shifting fibers (WLS) on its top and bottom faces, readout by Silicon Photomultipliers (SiPMs). Ionizing particles and absorbed gamma rays will leave energy...
The ATLAS Zero Degree Calorimeters (ZDCs) detect neutral particles emitted at very forward rapidities in nuclear collisions at CERN's Large Hadron Collider (LHC). During Runs 1 and 2 of the ATLAS experiment, the ZDCs have been crucial for identifying spectator neutrons in lead-lead collisions and in selecting ultraperipheral collisions.
The ZDCs consist of modules of sampling hadronic...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The scintillators are read-out by the wavelength shifting fibres coupled to the photomultiplier tubes (PMTs). The analogue signals from the PMTs are amplified, shaped, digitized by sampling the signal every 25...
The “muon-to-electron conversion” (Mu2e) experiment at Fermilab will search for the Charged Lepton Flavour Violating neutrino-less coherent conversion of a muon into an electron in the field of an aluminum nucleus. The observation of this process would be the unambiguous evidence of physics beyond the Standard Model. The detector has been designed as a state-of-the-art crystal calorimeter and...
In the context of the European strategy for particle physics, a multi-Tev muon collider has been proposed as a powerful tool to investigate the Standard Model with unprecedented precision, after the full exploitation of the High-Luminosity LHC. Being muons not stable particles, the main foreseen challenge is to distinguish collisions from the background radiation induced by decaying muons in...
Following the demand for precise measurements of the Higgs, Z/W bosons and the top quark, future lepton colliders, e.g. the Circular Electron Positron Collider (CEPC), are required to meet stringent requirements on the calorimetry systems to achieve unprecedented jet energy resolutions. As part of CEPC’s “4th detector concept”, a novel high-granularity crystal electromagnetic calorimeter...
While the Large Hadron Collider and its detectors are preparing for major upgrades in view of the high luminosity frontier, the high energy physics international community has started to look beyond the LHC. As recognized by the 2020 European Strategy Particle Physics Update, the pursuit of an electron-positron collider is one of the top priorities to study in detail the properties of the...
The Upgrade-2 of the LHCb experiment aims to operate with an instantaneous luminosity a factor seven higher than the current one to reach ultimate precision in several domains of its physics program. This objective challenges the development of subdetectors able to cope with the foreseen high-occupancy regime.
The measurement of the time of hits in the detector will be a crucial new feature....
Fermilab is one of the largest producers of organic scintillator in the world. Its scintillator has been used in a wide variety of applications including archeology, volcanology, mining exploration, agriculture, national security, as well as more traditional applications in HEP and Astro-particle physics. We will survey these applications. We will describe the scintillator extrusion facility...
The Electromagnetic Calorimeter (ECAL) serves as a subdetector for the HADES (High Acceptance Di-Electron Spectrometer) experiment, located at the FAIR-GSI in Darmstadt, Germany. The HADES experiment aims to study the QCD phase diagram at high baryonic densities and low temperatures, primarily via the di-lepton decay of vector mesons. The primary function of the ECAL is to measure the energy...
While many current world-leading experiments utilise dual-phase noble element time projection chambers (TPC) to perform direct dark matter searches, a potential alternative that may be simpler and easier to scale-up is a single-phase TPC. However, achieving proportional scintillation and charge amplification directly in the liquid is challenging due to the electric fields required, but could...
High granularity 3D calorimeters offer the potential to precisely reconstruct the 3D topology of electromagnetic and hadronic showers originating from isotropic sources. This distinctive capability creates the opportunity for applying reconstruction and analysis methods that could yield additional information compared to those based on the traditional layer-by-layer energy deposit analysis...
The precision measurements planned at future lepton colliders require excellent energy resolution especially in multi-jet events to successfully separate Z, W, and Higgs decays. Especially in hadronic decays, the resolution is largely limited by event-to-event fluctuations in the shower development. By compensating for these fluctuations, it is possible to improve the energy resolution...
DUNE experiment at Fermi National Accelerator Laboratory is mainly devoted in study of neutrino mass ordering and CP symmetry violation in the leptonic sector. The experiment comprises three main components: a high-intensity neutrino source, a massive Far Detector situated 1.5km underground at the Sanford Underground Research Facility in South Dakota, about 1300km far from neutrino source, and...
The ALICE Collaboration is planning to install a new forward calorimeter (FoCal) as a detector upgrade to the ALICE experiment at LHC during the next long shutdown from 2027 to 2029. The FoCal consists of a Si+W electromagnetic component with longitudinal segmentation (FoCal-E) and a conventional scintillating fiber hadronic component (FoCal-H). It will cover the pseudorapidity interval of...
Inorganic scintillators are widely used to build compact and high energy
resolution homogeneous electromagnetic calorimeters. In recent years, several
studies have been performed on the fact that their crystalline nature can heavily
affect the Bremsstrahlung and Pair Production mechanisms. In fact, experimen-
tal tests have shown that when the incident beam is aligned with the crystal...
The POKER (POsitron resonant annihilation into dark mattER) project aims to perform a missing-energy measurement employing a positron beam impinging on an active thick target. The beam interaction with the target could produce feebly interacting massive particles, exiting from the detector and carrying away a significant fraction of the primary positron energy. The crucial element of the POKER...
The SHADOWS experiment, proposed for the 400 GeV/c proton beam at CERN SPS, is dedicated to explore feebly interacting particles (FIPs) generated during proton interactions. This contribution specifically focuses on advancements related to the electromagnetic calorimeter of SHADOWS. In addressing the challenge of reconstructing particles that decay into photons, we present a conceptual design...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The High-Luminosity phase of LHC, delivering five times the LHC nominal instantaneous luminosity, is expected to begin in 2029. TileCal will require new electronics to meet the requirements of a 1 MHz trigger,...
