摘要：

轻子散射是研究核子和原子核等小粒子内部结构的理想工具。中国电子-离子对撞机（EicC）是未来高能核物理的重要项目。它将基于目前正在建设的升级重离子加速器，高强度重离子加速器设施（HIAF）以及新的电子环。拟议的对撞机将提供高度极化的电子（与$\sim$ 80%的极化）和质子（与$\sim$ 70%的极化）与可变的质心能量从15至20 GeV和（2-3）$\times$ 10 $^{33}$ cm $^{-2}$ s $^{-1}$。极化的氘核和氦-3，以及从碳到铀的非极化离子束，也将在EicC上提供。EicC的主要焦点将是海夸克区核子结构的精确测量，包括核子的三维层析成像;核的部分子结构和部分子与核环境的相互作用;奇异态，特别是具有重味夸克含量的奇异态。此外，理解质量起源的根本问题可以通过测量EicC的重夸克偶素近阈值产生来解决。为了实现上述物理目标，将利用尖端技术建造一个密封探测器系统。这份文件是全球专家集体贡献和宝贵投入的结果。EicC物理计划补充了杰斐逊实验室正在进行的科学计划和美国未来的EIC项目。该项目的成功也将推动中国的核物理和粒子物理以及加速器和探测器技术的发展。

英文摘要：

Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei. As a future high energy nuclear physics project, an Electron-ion collider in China (EicC) has been proposed. It will be constructed based on an upgraded heavy-ion accelerator, High Intensity heavy-ion Accelerator Facility (HIAF) which is currently under construction, together with a new electron ring. The proposed collider will provide highly polarized electrons (with a polarization of $\sim$80%) and protons (with a polarization of $\sim$70%) with variable center of mass energies from 15 to 20 GeV and the luminosity of (2-3) $\times$ 10$^{33}$ cm$^{-2}$ s$^{-1}$. Polarized deuterons and Helium-3, as well as unpolarized ion beams from Carbon to Uranium, will be also available at the EicC. The main foci of the EicC will be precision measurements of the structure of the nucleon in the sea quark region, including 3D tomography of nucleon; the partonic structure of nuclei and the parton interaction with the nuclear environment; the exotic states, especially those with heavy flavor quark contents. In addition, issues fundamental to understanding the origin of mass could be addressed by measurements of heavy quarkonia near-threshold production at the EicC. In order to achieve the above-mentioned physics goals, a hermetical detector system will be constructed with cutting-edge technologies. This document is the result of collective contributions and valuable inputs from experts across the globe. The EicC physics program complements the ongoing scientific programs at the Jefferson Laboratory and the future EIC project in the United States. The success of this project will also advance both nuclear and particle physics as well as accelerator and detector technology in China.
