Hint
Answer
What is this process called? - An inner shell electron is absorbed by a proton in the nucleus. The proton is transformed into a neutron and a neutrino is emitted
Electron capture
How much can strangeness change by in a weak interaction?
-1, 0 or +1
What is the interaction responsible for the decay of strange particles
Weak interaction
What is the interaction responsible for the production of strange particles.
Strong interaction
Which leptons are subject to the electromagnetic interaction
Electrons and muons
Which mesons decay through the weak interaction
Kaons
Name the quantities that are conserved in all particle interactions.
Charge, Momentum, Mass-energy, Lepton number, Baryon number
Particle not subject to the strong or electromagnetic interaction are called?
Neutrino
Particles with a baryon number of zero are called?
Leptons and mesons
Hint
Answer
Particles with a lepton number of zero are called?
Baryons and mesons (all hadrons)
Quantum number that is not always conserved is called
Strangeness
Strangeness is not conserved during a decay via what fundamental force?
Weak interaction
Quantum numbers that are always conserved are called
Lepton and baryon
Reason why a neutrino can't interact through the electromagnetic interaction
It has no charge
