The discovery of hadronic states beyond the conventional two-quark meson and three-quark baryon picture in the last two decades is one of the most amazing accomplishments in fundam…
Novel method for identifying the heaviest QED atom
Jing-Hang Fu, Sen Jia, Xing-Yu Zhou +3
The bound state of a pair by the electromagnetic force is the heaviest and smallest QED atom. Since the discovery of the two lightest QED atoms more than 60 years ago, no…
