Particles - Quarks and Leptons (Module 2) Flashcards
What can a kaon decay into?
They can decay into:
- Pions
- A muon and an antineutrino
- An antimuon and a neutrino
What can a charged pion decay into?
They can decay into:
- A muon and an antineutrino
- An antimuon and a neutrino
What does a pion with zero charge (π^0) decay into?
They decay into high energy photons
What does a muon and an antimuon decay into?
A muon decays into an electron, an electron antineutrino (antineutrino) and a muon neutrino. An antimuon decays into a positron, an electron neutrino (neutrino) and a muon antineutrino
What type of interactions can a neutrino interact through?
Weak
What type of interactions can pions and kaons interact through?
Strong and electromagnetic
Is a muon a hadron or a lepton?
Lepton
Name the two groups of particles under hadrons
Baryons and mesons
Explain what mesons are
They are hadrons that do not include protons in their decay (eg pions and kaons). They consist of one quark and one antiquark

+1/3
State the charge of a down quark
-1/3
State the strangeness of a strange quark
-1
State the baryon number of an antiup quark
-1/3
State the quark combination of an antiproton
Antiup, antiup, antidown
State the quark combination of a negatively charged pion (π^-)
Antiup, down
