摘要

大型强子对撞机的ALICE实验旨在探索夸克-胶子等离子体在超相对论性重离子碰撞中产生的热而致密的介质的性质。ALICE实验的光子光谱仪（PHOS）是一种高粒度电磁PbWO \({}_{4}\)晶体量热计，用于测量不同碰撞系统中的中性介子光谱和直接光子。我们报告了运行2和运行3期间PHOS性能的概述，并介绍了ALICE在pp和p-Pb碰撞中中性介子测量的最新结果。

Performance of the Electromagnetic Calorimeter ALICE/PHOS and Neutral Meson Production Results

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.
