The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observed in nuclear experiments using only quarks and gluons. However, it is only now that physicists, including those from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, have succeeded in doing this.
Thank you! So the image - is an illustration? I wasn’t clear on that either.
Pretty sure that’s the case and it’s just a deliberately misleading clickbait headline. The article and the paper both don’t reference anything about creating an actual image.
