Editing Hadron (section)

==Terminology and etymology==
The term "hadron" is a [[new Greek]] word introduced by [[Lev Okun|L. B. Okun]] in a [[plenary talk]] at the 1962 [[International Conference on High Energy Physics]] at [[CERN]].<ref name=Okun-1962-CERN-plenary/> He opened his talk with the definition of a new category term:
{{blockquote|Notwithstanding the fact that this report deals with weak interactions, we shall frequently have to speak of strongly interacting particles. These particles pose not only numerous scientific problems, but also a terminological problem. The point is that "''strongly interacting  particles''" is a very clumsy term which does not yield itself to the formation of an adjective. For this reason, to take but one instance, decays into strongly interacting particles are called "non-[[leptonic]]". This definition is not exact because "non-leptonic" may also signify photonic. In this report I shall call strongly interacting particles "hadrons", and the corresponding decays "hadronic" (the Greek {{lang|grc|ἁδρός}} signifies "large", "massive", in contrast to {{lang|grc|λεπτός}} which means "small", "light"). I hope that this terminology will prove to be {{nowrap|convenient. — [[Lev Okun|L. B. Okun]] (1962)<ref name=Okun-1962-CERN-plenary/>}}
