Parallel session 2: Detectors & future experiments
- W.A. Zajc (Columbia University)
The ALICE Collaboration has proposed a completely new apparatus, ALICE 3, for the LHC Run 5 (LoI, arXiv:2211.02491). The detector consists of a large pixel-based tracking system covering eight units of pseudorapidity, complemented by multiple systems for particle identification, including silicon time-of-flight layers, a ring-imaging Cherenkov detector, a muon identification system, and an...
Owing to its spectrometer acceptance, unique with respect to the other LHC experiments, and to its excellent tracking and particle identification, LHCb has been developing since the LHC Run2 a complete heavy-ion programme. In parallel, by exploiting the injection of gases in the LHC accelerator beam-pipe, LHCb is now simultaneously acquiring data in collider and fixed-target mode, with two...
The intriguing phenomena emerging in high-density quantum chromodynamics (QCD) matter are being extensively studied in the LHC’s heavy ion program, and will be explored in greater depth during the high-luminosity LHC (HL-LHC) era. To meet the challenges of HL-LHC, the CMS experiment is undergoing significant Phase-2 upgrades, including the MIP Timing Detector (MTD), which provides 30 ps timing...
A new fixed-target experiment, NA60+, is proposed at the CERN SPS to measure muon pairs in the centre-of-mass energy range from 6 to 17 GeV across various collision systems, from Pb--Pb to p--Be. Its physics scope spans topics from thermal radiation, to chiral symmetry restoration, strangeness, and charm production.
The experimental apparatus comprises a vertex spectrometer and a...
The Compressed Baryonic Matter (CBM) experiment is under construction at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It aims to explore the phase structure and microscopic properties of strong interaction (QCD) matter at large net-baryon densities and moderate temperatures using heavy-ion collisions in the energy range √sNN = 2.9 - 4.9 GeV.
CBM is a...
The FoCal is a high-granularity forward calorimeter to be installed as an ALICE upgrade during the LHC Long Shutdown 3 and take data in Run 4. It will cover a pseudorapidity interval of $3.2 < \eta < 5.8$, allowing to explore QCD at unprecedented low Bjorken-$x$ of down to $\approx 10^{-6}$ - a regime where non-linear QCD dynamics are expected to be sizable.
The FoCal consists of a compact...
A subset of heavy-ion collisions are ultra-peripheral collisions (UPC), where the ions collide with a large impact parameter, causing them to interact primarily through their intense electromagnetic fields. These interactions allow for the study of various photon-induced processes at high energies. The products of exclusive UPC interactions are typically characterized by very low transverse...
