Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Quark yeimwe flavour inogona kushanduka kuva quark yeimwe flavour bedzi kupfurikidza nokubatana kusina kusimba, kumwe kwokubatana kwokutanga muparticle physics. Nokupinza kana kubudisa W boson, chero up-type quark (up, charm, uye top quarks) inogona kuchinja kuva chero down-type quark (down, strange, uye bottom quarks) uye zvinopesana. Iyi nzira yokushandurwa kwokunhuwira inokonzera muitiro we radioactive we beta kuora, umo neutron (n) "inoparadzanisa" muproton (p), electron (e−) uye electron antineutrino (νe) (ona mufananidzo). Izvi zvinoitika apo imwe ye down quarks iri mu neutron (udd) inoparara kuva up quark nokuburitsa W− boson chaiyo, ichishandura neutron kuva proton (uud). W− boson inobva yadzikira kuva elektroni uye antineutrino yemagetsi.  Mubvunzo: W-boson inoora kuva chii?
electron uye electron antineutrino
