Structura del quarks de un neutron.

In physica de particulas le quark (/ˈkwark/) esse un fermion, particula elementari que participa al interaction forte.

Le quark habe un carga electric de +2/3 o −1/3 (le antiquark −2/3 o +1/3) e spin 1/2. In natura illos non se trova isolate, sed solmente unite in particulas composite nominate hadrones, como per exemplo le proton e le neutron.

Nomine Carga Massa estimate (MeV/c2)
Supra (u) up +2/3 de 1,5 a 4 1
Duna (d) down -1/3 de 4 a 8 1
Estranie / Oblique (s) strange -1/3 de 80 a 130
Charme / Incanto / Centro (c) charm +2/3 de 1 150 a 1 350
Alto / Ver / Veritate (t) top +2/3 174 300 ± 5 100
Basso / Belle / Beltate (b) bottom -1/3 de 4 100 a 4 400
