高能质子与核形状涨落研究综述

Review of proton and nuclear shape fluctuations at high energy

Heikki Mäntysaari

摘要:

根据质子和原子核的基本组成确定它们的内部结构一直是高能核物理和粒子物理实验的主要任务之一。这个探索开始于作为纵向动量分数和分辨率尺度的函数的(平均)部分子密度的映射。最近,该领域已经发展到更多的微分成像,其中一个重要的发展是在碰撞强子的波函数事件的量子涨落的描述。本文综述了从高能对撞机实验中提取质子和具有逐事件涨落的核横截面几何的最新进展。这从根本上有趣的物理学在其他对撞机实验中的重要性,如在夸克-胶子等离子体的性质的研究也说明了。

英文摘要:

Determining the inner structure of protons and nuclei in terms of their fundamental constituents has been one of the main tasks of high energy nuclear and particle physics experiments. This quest started as a mapping of the (average) parton densities as a function of longitudinal momentum fraction and resolution scale. Recently, the field has progressed to more differential imaging, where one important development is the description of the event-by-event quantum fluctuations in the wave function of the colliding hadron. In this Review, recent developments on the extraction of proton and nuclear transverse geometry with event-by-event fluctuations from collider experiments at high energy is presented. The importance of this fundamentally interesting physics in other collider experiments like in studies of the properties of the Quark Gluon Plasma is also illustrated.
