Abstract An electron ion collider has been proposed in China (EicC). It is anticipated that the facility would provide polarised electrons, protons and ion beams, in collisions with large centre-of-mass energy. This discussion highlights its potential to address issues that are central to understanding the emergence of mass within the Standard Model, using examples that range from the exploration of light-meson structure, through measurements of near-threshold heavy-quarkonia production, and on to studies of the spectrum of exotic hadrons.

1 Introduction No single date can be identified as the beginning of the modern era in nuclear and particle physics; but one can, perhaps, associate the dawning of this new age with discovery of the proton [1–4]. Today, one century and more than fifty Nobel Prizes later, the Standard Model of Particle Physics (SM) [5] “…offers a description of all known fundamental physics except for gravity, and gravity is something that has no discernible effect when particles are studied a few at a time.” With discovery of the Higgs boson [6,7
