ALICE is a general-purpose, heavy-ion detector at the CERN LHC which focuses on quantum chromodynamics. It is designed to address the physics of strongly interacting matter and the quark-gluon plasma at extreme values of energy density and temperature in nucleus-nucleus collisions. In addition, it has a rich physics program for proton-proton and proton-nucleus collisions.
In this overview,...
The NA60+ experiment has been proposed as a fixed-target experiment for the study of quark-gluon plasma (QGP) in heavy-ion collisions.
Its aim is a precise of study hard and electromagnetic processes at high baryochemical potential from 200 to 550 MeV at the CERN SPS. The experiment plans to perform measurements of thermal dimuons, charmed hadrons, strange particles and hypernuclei production...
Among the most iconic results of Run 1 and Run 2 of the LHC is the observation of enhanced production of (multi-)strange to non-strange hadron yields, gradually rising from low-multiplicity to high-multiplicity pp or p--Pb collisions and reaching values close to those measured in peripheral Pb--Pb collisions. More insightful information about the production mechanism could be provided by...
Strongly interacting matter at high temperature and densities turns into a deconfined medium known as the Quark-Gluon Plasma. The combined effort of theory and experiment has helped shed light on its features, as well as on the phase structure of matter in such extreme conditions.
Heavy-ion collisions now routinely create short-lived Quark-Gluon Plasma droplets, and can explore the phase...
The formation mechanism of light (anti)nuclei produced in high-energy hadronic collisions is an open question that is being addressed both theoretically and experimentally. Moreover, the study of (anti)nuclei production at particle accelerators is relevant to model the flux of antinuclei produced in cosmic ray interactions, which represents the dominant background for dark matter searches. In...
The ALICE experiment at the Large Hadron Collider (LHC) at CERN has planned an upgrade of the Inner Tracking System (ITS), called ITS3, which will be installed during the LHC Long Shutdown 3 (2026-2028). The upgrade will implement a new 65 nm CMOS Monolithic Active Pixel Sensor (MAPS) employing the stitching technology to create wafer-scale chips up to 26 cm long. The produced chips will be...
The ALICE collaboration is proposing a new apparatus, ALICE 3, to investigate the Quark Gluon Plasma properties for the LHC Runs 5 and 6. The measurements planned to address ALICE 3 physics goals require to identify charged particles over eight units of pseudorapidity ($|\eta|<4$) and to achieve a better than 3$\sigma$ $e$/$\pi$, $\pi$/$K$ and $K$/$p$ separation up to above 2 GeV/$c$, 10...
Silicon PhotoMultipliers (SiPMs) are established photon detectors for a variety of applications because of their high efficiency, insensitivity to magnetic fields and low cost. In High Energy Physics (HEP) applications, SiPMs are usually coupled to scintillators or Cherenkov radiators. Nonetheless, it has been observed that SiPMs are able to directly detect charged particles: at the passage of...
Ultra-peripheral heavy-ion collisions (UPCs) occur when the impact parameter of the collision is greater than the sum of the radii of the colliding nuclei. Given the short range of the strong force, these collisions allow one to study photoninduced reactions. Of particular interest is the photoproduction of a vector meson, that is a well-established tool to probe the gluon structure of the...
The ALICE Collaboration has submitted a proposal for a next-generation heavy-ion experiment, named ALICE 3, to be installed during the LHC Long Shutdown 4. The key features of this new experimental apparatus will be an exceptional pointing resolution and an excellent Particle IDentification (PID) capability. A Time-Of-Flight system, made of silicon sensors, with an outstanding time resolution...
