论文摘要
在PP和LHC处的重离子碰撞中相关的颗粒产生过程特别有趣，因为它们提供了研究双方散射（DPS）机制的独特工具。在本演讲中，我将首先回顾DPS在PP碰撞中的最新理论，现象学和实验发展。然后，我将重点介绍重离子碰撞中的DPS研究，并强调其在理解冷核物质效应中的作用，例如（（众所周知的）影响 - 参数依赖性核parton密度。
Associated particle production processes in pp and heavy ion collisions at the LHC are in particular interesting in the sense that they provide unique tools to study double parton scattering (DPS) mechanism. In this talk, I will first review the recent theoretical, phenomenological and experimental developments of DPS in pp collisions. Then, I will focus on the DPS studies in heavy ion collisions, and stress their roles in understanding the cold nuclear matter effects, such as the (poorly known) impact-parameter dependent nuclear parton densities.
