Ọ bụrụ na a na-atụgharị quark n'ime quark nke ọzọ, ọ ga-abụ naanị site na mmekọrịta na-adịghị ike, otu n'ime ihe anọ dị mkpa na physics nke ụmụ irighiri ihe. Site na absorption ma ọ bụ na-ekpughe a W boson, ọ bụla elu-ụdị quark (elu, amara, na top quarks) nwere ike ịgbanwe n'ime ọ bụla ala-ụdị quark (ala, weird, na ala quarks) na vice versa. Nke a flavor mgbanwe usoro na-akpata radioactive usoro nke beta decay, nke a neutron (n) "na-ekewa" n'ime a proton (p), na electron (e-) na ihe electron antutrino (νe) (lee foto). Nke a na-eme mgbe otu n'ime quarks na neutron (ala) decays n'ime quark site na-ekpughe a virtual W− boson, na-agbanwe proton n'ime a neutron (Wud).
