Ninu fisiksi eleruku, awon bosoni ( /ˈboʊsɒn/) je eruku inuatomu pelu nomba odidi spin (s = 0, 1, 2 etc.) ti won tele ilana statistiki Bose-Einstein. Oruko bosoni wa latowo Paul Dirac lati se eye fun ipa ti asefisksi ara India Satyendra Nath Bose, pelu Albert Einstein, ko ninu idasile statistiki Bose-Einstein—arojinle to unselana ninu eyi. Ninu awon Bosoni ni bosoni Higgs (s=0), awon mesoni (s=0,1), grafitoni aladalaba (s=2), iyewu adurosinsin nomba akojo didogba (f.a., deuterium, helium-4, lead-208) ati awon aruku to pondandan lati se papa arojinle papa oniyebintin bi awon fotoni, awon gluoni, at.b.b.lo. Awon bosoni yato gidigidi si awon eka eruku inu atomu ti a mo si fermioni nibi pe ko si opin si iye to le wa ni aye oniyebintin kanna. Iwa yi, fun apere, lo unfa ini pataki helium-4 nigba to ba je titutu de superfluid. Bosons contrast with fermions, which obey Fermi–Dirac statistics. Two or more fermions cannot occupy the same quantum state (see Pauli exclusion principle).
