Fermions feem ntau cuam tshuam nrog teeb meem, qhov bosons feem ntau yog quab yuam cov khoom thauj, txawm hais tias nyob rau hauv lub xeev tam sim no ntawm particle physics qhov txawv ntawm ob lub tswv yim tsis meej. Kev sib cuam tshuam fermions tsis muaj zog tuaj yeem pom tus cwj pwm bosonic nyob rau hauv qhov xwm txheej hnyav.

Puas yog bosons force carriers?

W thiab Z bosons yog cov neeg nqa khoom quab yuam uas kho qhov tsis muaj zog. Gluons yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob hauv qab lub zog muaj zog. Higgs bosons muab W thiab Z bosons (thiab lwm yam) loj ntawm Higgs mechanism. Lawv lub neej tau lees paub los ntawm CERN ntawm 14 Lub Peb Hlis 2013.

plaub lub zog nqa li cas?

Kev quab yuam thiab cov khoom nqa khoom

Muaj plaub lub zog ua haujlwm hauv lub ntiaj teb: lub zog muaj zog, lub zog tsis muaj zog, lub zog hluav taws xob, thiab lub zog gravitational.

Dab tsi yog lub zog nqa hauv lub atom?

Tus neeg nqa khoom quab yuam tuaj yeem xa cov lus sib txawv. Protons thiab electrons, uas muaj cov nqi sib txawv, yog nyiam ib leeg los ntawm lub zog hluav taws xob. Cov khoom uas nqa lub zog ntawd, hu ua photons, ua zoo li ntawv hlub. Lawv kos cov protons thiab electrons ua ke.

Qhov txawv ntawm fermions thiab boson yog dab tsi?

A fermion yog ib qho khoom uas muaj qhov khib ib nrab ntawm cov lej (xws li 1/2, 3/2, thiab lwm yam) tig. … Bosons yog cov particles uas muaj ib tug integer spin (0, 1, 2…). Tag nrho cov khoom siv hluav taws xob muaj zog yog bosons. Cov fermions tau pom tias ua raws li Pauli cais tawm txoj cai thiab ua raws li Fermi-Dirac cov txheeb cais.
