classification of particles

what do all particles have

• hadrons

• leptons

what is the difference between leptons and hadrons

leptons are fundamental particles

what do all particles have

• hadrons

• leptons

what is the difference between leptons and hadrons

leptons are fundamental particles

what do leptons not experience

strong nuclear force

what can hadrons be broken down into

• baryons

• antibaryons

• mesons

what are baryons formed from

3 quarks

what are antibaryons formed from

3 antiquarks

what are mesons formed from

a quark and antiquark

what are examples for leptons

electron, muon, electron neutrino and their antiparticles

what are examples of baryons

proton and neutrons

what are examples of mesons

pion and kaon

what does the baryon number show

it is a baryon (if 1), antibaryon (if -1) or not a baryon (if 0)

when is the baryon number conserved

in particle interactions

what is the only stable baryon

proton

what does the lepton number show

it is a lepton (if 1), antilepton (if -1) or not a lepton (if 0

when is the lepton number conserved

in particle interactions

what is a muon known as

a heavy electron

what do muons decay into

electrons

what are strange particles

produced by the strong nuclear interaction but decay by the weak interaction

what is a property of particles

strangeness

what are strange particles always created in

pairs

what particle physics rely on

collaborative efforts of large teams of scientists and engineers to validate new knowledge.
