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 ∼80%) and protons (with a polarization of ∼70%) with variable center of mass energies from 15 to 20 GeV and the luminosity of (2-3) × 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.

Exclusive production of charmonium-like XYZ states in hadron-hadron ultraperipheral collisions(UPCs) and electron-proton scattering is studied employing effective Lagrangian method. Total cross sections and rapidity distributions of charmonium-like XYZ states are obtained in hadron-hadron UPCs and electron-proton scattering process. These predictions can be applied to estimate the observed event number of exclusive charmonium-like XYZ states in hadron-hadron UPCs and electron-proton scattering. The results indicate that it is significant to search X(3872) and Z + c (3900) in pA UPCs and Electron-Ion Collider in China will be an advantage platform to observe XYZ states in the future.

Decays of charmonia(-like) particles with definite JPC (e.g. χc1(3872)) to a $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 system and any combination of C-definite decay particles, are sources of quantum-correlated $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems with C = P = ±1. Several b-hadron decays also produce quantum-correlated $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems. Advantages of isolating these systems in their C = +1 components for amplitude analyses and studies of lineshapes are discussed. Methods to separate the C = ±1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 components from χc1(3872) decay samples are presented. Studies of T and CPT conservation in C = +1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems can be performed with more easily reconstructible final states, when compared to C = −1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems. Experimental mechanisms that can produce C = ±1 $$ {D}^0{\overline{D}}^0 $$ D 0 D ¯ 0 systems are described in an appendix.
