Cov huab hwm coj (lossis sib npaug, lub zog so) ntawm neutrino tseem tab tom ua haujlwm tab sis peb paub tias qhov hnyav tshaj plaws ntawm neutrino hnyav tsawg kawg yog 30 npaug tsawg dua li proton lossis neutron (lossis tsawg kawg 10 npaug me duaquark).
Puas yog neutrino qhov tsawg tshaj plaws?
Ib neutrino yog ib qho subatomic particle uas zoo ib yam li electron, tab sis tsis muaj hluav taws xob thiab ib pawg me me, uas tej zaum yuav yog xoom. Neutrinos yog ib qho ntawm ntau tshaj plaws nyob rau hauv lub ntiaj teb no. Vim tias lawv muaj kev cuam tshuam me me nrog cov teeb meem, txawm li cas los xij, lawv nyuaj heev los kuaj xyuas.
Puas muaj dab tsi me dua li qhov quark?
In particle physics, preons yog cov ntsiab lus hais, xeeb los ntawm cov khoom sib txuas ntawm quarks thiab lepton. … Txhua tus qauv preon postulates ib pawg ntawm cov ntsiab lus tsawg dua li cov qauv qauv, nrog rau cov kev cai tswj xyuas seb cov ntsiab lus tseem ceeb sib xyaw ua ke thiab cuam tshuam li cas.
Dab tsi yog qhov me dua neutrino?
Ib qho hluav taws xob muaj ze-zero mass, tab sis nws hnyav 500, 000 npaug ntau dua li neutrino (dua, nws qhov ntsuas qhov tseeb tsis tuaj yeem ua rau ntawm qhov no). Cov kws kho mob siv cov hluav taws xob hluav taws xob (eV) los ntsuas qhov loj ntawm subatomic hais, Lincoln tau hais. Technically, chav tsev yog eV/c^2, uas c yog qhov ceev ntawm lub teeb.
Dab tsi yog qhov tsawg tshaj plaws?
Quarks yog tusqhov me me uas peb tau hla hauv peb txoj kev sim siab. Qhov Discovery ntawm quarks txhais tau hais tias protons thiab neutrons tsis yog qhov tseem ceeb ntxiv lawm.
