Abstract
The ALICE experiment at the LHC is designed to explore the properties of the quark–gluon plasma—hot and dense medium produced in ultrarelativistic heavy-ion collisions. The photon spectrometer (PHOS) of the ALICE experiment is a high-granularity electromagnetic PbWO\({}_{4}\) crystal calorimeter which is intended to measure neutral meson spectra and direct photons in different colliding systems. We report an overview of the PHOS performance during Run 2 and Run 3 and present recent results from ALICE on the neutral meson measurements in pp and p–Pb collisions.
期刊介绍:
Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
