摘要

本报告总结了欧洲粒子监测中心 "大型强子对撞机超低横动量和低质量下的真实和虚拟光子产生 "快速反应工作组的工作。我们概述了软光子之谜，即实验数据与基于洛氏软光子定理（也称为 "反常 "软光子产生）的预测之间长期存在的差异，并回顾了当前对软辐射和软定理的理论理解。我们还关注低质量二价子，将其作为确定高能核-核碰撞中产生的介质导电性的工具。我们将讨论如何利用计划中的大型强子对撞机 ALICE 3 探测器来解决这两个问题。

Anomalous soft photons: status and perspectives

This report summarizes the work of the EMMI Rapid Reaction Task Force on "Real and Virtual Photon Production at Ultra-Low Transverse Momentum and Low Mass at the LHC". We provide an overview of the soft-photon puzzle, i.e., of the long-standing discrepancy between experimental data and predictions based on Low's soft-photon theorem, also referred to as "anomalous" soft photon production, and we review the current theoretical understanding of soft radiation and soft theorems. We also focus on low-mass dileptons as a tool for determining the electrical conductivity of the medium produced in high-energy nucleus-nucleus collisions. We discuss how both topics can be addressed with the planned ALICE 3 detector at the LHC.
