Iyini i-spin ye-quark?
Context:Ama-fermion angenye yezinhlobo ezimbili eziyisisekelo zezinhlayiya, enye iyi-boson. Izinhlayiya ze-fermion zichazwe ngezibalo ze-Fermi<unk>Dirac futhi zinamanani e-quantum achazwe ngumgomo wokukhishwa kukaPauli. Zihlanganisa ama - quark nama - lepton, kanye nanoma yiziphi izinhlayiya ezihlanganisiwe ezinenani elingajwayelekile lalezi, njenge - baryons nama - athomu amaningi nama - nucleus.  Ama-fermion ane-half-integer spin; kuwo wonke ama-fermion ayisisekelo awaziwayo lokhu kungu-1⁄2. Wonke ama-fermion awaziwayo ngaphandle kwama-neutrinos, nawo angama-fermion kaDirac; okusho ukuthi, i-fermion ngayinye eyaziwayo ine-antiparticle yayo ehlukile. Akwaziwa ukuthi i-neutrino iyi-Dirac fermion noma i-Majorana fermion. Ama-fermion ayizakhi eziyisisekelo zawo wonke ama - matter. Zihlukaniswa ngokuthi ziyasebenzelana yini noma cha ngokusebenzisa indlela yokulinganisa enamandla. Kumodeli Oyisisekelo, kunezinhlobo ezingu-12 zama-fermion ayisisekelo: ama-quark ayisithupha nama-lepton ayisithupha.
Ama-quark ane-spin 1/2 ngoba angama-fermion.
