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.

Lwm yam sib npaug, hnyav skier nrawm dua tus sib duavim nws huab cua qis dua. Yog li, tus neeg caij ski tuaj yeem mus nrawm dua los ntawm kev nce huab hwm coj - ua hnyav npaum li qhov ua tau rau nws tus ncej. Tsuas yog li ntawm 200 phaus xwb qhov zoo ntawm qhov hnyav ntxiv tau tshem tawm los ntawm kev sib txhuam ntxiv nrog cov daus.
Puas siab dua lossis qis dua snr zoo dua?
Yuav kom ua tiav qhov kev sib txuas txhim khu kev qha, theem teeb liab yuav tsum muaj ntau dua li lub suab nrov. Ib qho SNR ntau dua 40 dB yog suav tias yog qhov zoo tshaj plaws, qhov SNR qis dua 15 dB yuav ua rau qeeb, tsis muaj kev sib txuas.
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. Lo lus tau tsim los ntawm Jogesh Pati thiab Abdus Salam, xyoo 1974. Puas yog quark Qhov tsawg tshaj plaws? Quarks yog ntawm cov khoom me tshaj plaws hauv lub ntiaj teb, thiab lawv nqa tsuas yog cov nqi hluav taws xob xwb.
Rau kev nyeem tau zoo dua nws yog qhov zoo dua tias cov ntsiab lus mos txwv yog?
Kua koj cov ntsiab lus mos txwv symmetrical Yog ua tau Lub ntsiab lus, ib kab ib, ob kab ib, thiab lwm yam. Nws yooj yim dua ntawm lub qhov muag thiab yog li yooj yim ntawm tus nyeem. Thaum twg koj yuav tsum siv cov ntsiab lus mos txwv?
Puas yog lo lus nyab xeeb dua lossis puas nyab xeeb dua?
Ib qho ntawm cov lus nug feem ntau cov qauv sau ntawv yog hais txog daim ntawv sib piv ntawm lo lus "kev nyab xeeb." Puas yog "kev nyab xeeb dua?" los yog "kev nyab xeeb dua?" Hauv Teb Chaws Asmeskas, ob qho tib si siv tau, tab sis "
