Baryons yog fermions, thaum mesons yog bosons. Dhau li ntawm tus nqi thiab tig (1/2 rau baryons), ob tug lej quantum tau muab rau cov khoom no: baryon tooj (B=1) thiab txawv txawv (S), uas nyob rau hauv daim ntawv yuav pom tau tias yog sib npaug rau -1 npaug ntawm cov quarks txawv txawv suav nrog.
Dab tsi muaj qhov txawv?
Nyob zoo ib tsoom phooj ywg sawv daws
- Nucleons.
- Quarks.
- YProtons.
- Form Factors.
- Hyperons.
- Baryons.
- Kev sib tsoo.
- Kaons.
Yuav ua li cas paub yog hais tias ib tug particle muaj txawv?
Peb tuaj yeem pom qhov txawv ntawm qhov particle los ntawm kev siv txoj cai ntawm kev txuag kev txawv txawv. Piv txwv li, nyob rau hauv ib qho kev tshwm sim uas ib tug tsis zoo-them pion cuam tshuam nrog ib tug proton, ib tug nruab nrab kaon thiab ib tug nruab nrab lambda particle yog tsim.
Yuav ua li cas quark muaj qhov txawv ntawm?
Ntawm rau qhov tsw ntawm quarks, tsuas yog lub quark coj txawv txawv muaj qhov tsis txawv txav. Qhov txawv ntawm nucleons yog zero, vim tias lawv tsuas muaj nce thiab nqis quarks thiab tsis muaj qhov txawv txav (tseem hu ua sideways) quarks. Yog xav paub ntxiv mus saib daim duab Tus Qauv Qauv ntawm Cov Ntsiab Lus Tseem Ceeb thiab Kev Sib Raug Zoo.
Txhua tus meson puas muaj qhov txawv?
mesons. Tag nrho cov nyob rau hauv tag nrho, tus nqi ntawm qhov txawv txav tuaj yeem hloov pauv hauv qhov tsis muaj zog cuam tshuam los ntawm +1, 0 lossis -1 (nyob ntawm cov tshuaj tiv thaiv). Ntawm no kev txawv txav tau txuag thiab kev sib cuam tshuamua tiav los ntawm lub zog muaj zog nuclear.
