By the mid-1960s a multitude of nuclear particles were discovered and one of the most important scientific issues was what the fundamental elements of the substance were. The proton dispersion experiments from protons from the early 1970s made it clear that hadrons were not elemental objects. on the other side of Hadron spectrum research.
Murray Gell-Mann and George Weing independently suggested that all. These particles are made of quartz. for a long time the quartz was considered only as a good mathematical way for the evaluation of quantum numbers and not as true physical bodies. Despite the hadrons, for leptons, there is still no evidence of the existence of their structure. So today it is assumed that leptonites are elemental particles while hadrones are made up of essential ingredients of matter. The Standard Model is the exact mathematical theory of the motion of small particles of matter – elemental particles whose predictions agree with the results of many experiments.
