Quarks And Leptons Flashcards
What do charges pi mesons decay into?
Muons and antineutrinos or antimuons and neutrinos
What do K mesons decay into?
pi mesons, muons and antineurinos, and antimuons and neutrinos
What do neutral pi mesons decay into?
High energy photons
What do muons and antimuons decay into?
Electrons and antineutrinos or positrons and neutrinos
What is a hadron?
Interacts through strong nuclear force
What is a lepton?
Does not interact through strong nuclear force
What interaction do hadrons decay by?
Weak interaction
Whats a baryon?
Hadron, 3 quarks, decay into proton
Mesons?
Quark-antiquark, does not decay into proton
What can neutrino and antineutrino do in interaction between an hadron and a lepton?
They can change into or from a corresponding charged lepton
What happens in muon decay?
The muon changes into a muon-neutrino and an electron and an electron-neutrino are created
In what interaction is strangeness always conserved?
Strong interaction
What is the strangeness of a strange quark?
-1
