2.3- LEPTONS AT WORK Flashcards
How much do neutrino interact?
very little
How long do muons live?
short-lived
Do the electrons attract or repel one another?
repel
When leptons and antileptons interact what do they produce?
hadrons
What happens when a single electron-positron annihilation event occurs?
produces a quark and corresponding antiquark which move away in opposite directions, producing a shower of hadrons in each direction
How fast do hadrons travel?
almost as fast as light
Are neutrinos and antineutrinos produced in beta decays same as those produced by muon decays?
no they are different
How are the neutrinos produced from muon decays different from those produced in beta decays?
muon and antimuon decays create only muons and no electrons when they interact with protons and neutrons
What would it be like if there was only one type of neutrino and antineutrino?
equal numbers of muons and antimuons would be produced
How can leptons change into other leptons?
through the weak interaction and can be produced or annihilated in particle-antiparticle interactions
What do leptons not break down into?
non-leptons
What can happen in an interaction between a lepton and a hadron?
neutrino or antineutrino can change into or form a corresponding charged lepton
What can an electron neutrino interact with a neutron to produce?
proton and an electron
What happens to the muon in a muon decay?
muon changes into a muon neutrino
What is created in a muon decay?
an electron
