Existing standard hadrons and exotic hadrons. At the B Factory experiment, a series of new exotic mesons containing charm quarks (c) have been discovered. Unlike these exotic mesons, the newly discovered Zb particles contain bottom quarks (b) and have an electric charge. If only one bottom quark and one anti-bottom quark ( b ) are contained, the resulting particle is electrically neutral. Thus, the Zb must also contain at least two more quarks (e.g., one up quark (u) and one anti-down quark ( d )).

These new particles have electric charge and are thought to be "exotic" hadrons -- non-standard hadrons, containing at least four quarks. Previously, a series of new and unexpected exotic hadrons containing charm and anti-charm quarks have been observed. This latest discovery from Belle demonstrates the existence of exotic hadrons containing at least four quarks in a particle system including bottom quarks .</span></span></span></div><span style="background-color: white;
