Nyob rau hauv particle physics, ib tug massless particle yog ib tug elementary particle uas nws invariant loj yog xoomOb lub npe hu ua massless particles yog ob qho tib si gauge bosons: lub photon (carrier ntawm electromagnetism) thiab cov gluon (carrier ntawm lub zog muaj zog). Neutrinos yog thawj zaug xav tias tsis muaj dab tsi. …
Yuav ua li cas muaj ntau yam khoom muaj nyob?
Vim tias photons (particles ntawm lub teeb) tsis muaj huab hwm coj, lawv yuav tsum mloog E=pc thiab thiaj li tau txais tag nrho lawv lub zog los ntawm lawv lub zog. … Tab sis ib yam khoom uas tsis muaj zog thiab xoom loj tsis muaj dab tsi hlo li. Yog li ntawd, yog hais tias ib yam khoom uas tsis muaj huab hwm coj yog nyob rau hauv lub cev, nws yeej tsis tuaj yeem so
Puas muaj cov khoom tsis muaj huab cua?
Ob tus kws kho mob paub tias yog (tsawg kawg kwv yees li) tsis muaj zog- photons thiab gluons-yog ob qho tib si quab yuam-nqa, tseem hu ua gauge bosons.
Puas muaj cov khoom tsis muaj huab cua puas muaj qhov laj thawj?
Txawm li cas los xij lub photon yuav nyob twj ywm tsis muaj zog, txij li kev ntsuas qhov sib txawv yog qhov sib luag ntawm ob qho tib si ua thiab ntsuas. Tam sim no nyob rau hauv 'lub ntiaj teb tiag', qhov tig 1/2 lepton muaj cov cuab yeej uas lawv ob lub chiralities muaj qhov sib txawv tsis muaj zog: yog li cov lepton yuav loj heev. … Tias yog vim li cas massless nqi particle tsis tuaj yeem muaj
Yuav ua li cas lub photon tsis muaj huab hwm coj?
Vim li cas photons tsis muaj huab hwm coj? Nyob rau hauv luv luv, qhov tshwj xeeb txoj kev xav ntawm kev sib raug zoo kwv yees hais tias photons tsis muaj mass tsuas yog vim lawv mus ntawm qhov ceev ntawm lub teebQhov no kuj rov qab los ntawm txoj kev xav ntawm quantum electrodynamics, uas kwv yees tias photons. tsis tuaj yeem muaj huab hwm coj los ntawm U(1) -gauge symmetry.
