had·ron

 (hăd′rŏn′)
n.
Any of a class of subatomic particles that are composed of two or three quarks and participate in strong interactions. The class of hadrons is divided into the mesons and baryons.

[Greek hadros, thick; see sā- in Indo-European roots + -on.]

had·ron′ic adj.

hadron

(ˈhædrɒn)
n
(Nuclear Physics) any elementary particle capable of taking part in a strong nuclear interaction and therefore excluding leptons and photons
[C20: from Greek hadros heavy, from hadēn enough + -on]
hadˈronic adj

had•ron

(ˈhæd rɒn)

n.
any of a group of elementary particles subject to the strong interaction, subdivided into baryons and mesons.
