A hadron, in particle physics, is any subatomic (smaller than the atom) particle or antiparticle which is made of quarks. Quarks are fundamental particles which among other properties have an electrical charge and a name (e.g. 'up', 'down', 'strange'). The electrical charge of a single quark is always a fraction (e.g. 2/3).
Baryons, along with mesons, are hadrons, meaning they are particles composed of quarks. Quarks have baryon numbers of B = 1â3 and antiquarks have baryon number of B = â 1â3. The term baryon usually refers to triquarks âbaryons made of three quarks (B = 1â3 + 1â3 + 1â3 = 1).aryons, along with mesons, are hadrons, meaning they are particles composed of quarks.
