The states: experimental and theoretical status and perspectives
Nora Brambilla, Simon Eidelman, Christoph Hanhart +5
The quark model was formulated in 1964 to classify mesons as bound states made of a quark-antiquark pair, and baryons as bound states made of three quarks. For a long time all know…
