Gabaɗaya, ƙwayoyin halitta a cikin Tsarin Daidaitacce an rarraba su zuwa manyan rukuni biyu: fermions da bosons.
An ƙara raba fermions zuwa ƙungiyoyi biyu: quarks da leptons. Quarks su ne barbashi waɗanda ke samar da protons da neutrons, waɗanda kuma ke samar da ƙwayoyin atomic. Akwai nau'ikan quarks guda shida: sama, ƙasa, fara'a, abin mamaki, sama, da ƙasa. Leptons sun ƙunshi electrons, muons, taus, da neutrinos ɗinsu.
Bosons barbashi ne da ke shiga tsakani a cikin ƙarfin tushe. Misali, photons su ne masu ɗaukar ƙarfin lantarki, gluons su ne masu ɗaukar ƙarfin ƙarfi, kuma bosons na W da Z su ne masu ɗaukar ƙarfin rauni. Boson na Higgs, wanda aka sanar da gano shi a shekarar 2012 a CERN, ya samar da wata hanya da ke bayyana yadda ƙwayoyin halitta ke samun nauyinsu.
