Particle sorting, Contain one quark and one antiquark
They have a baryon…
-
- Contain one quark and one antiquark
- They have a baryon and lepton number of zero
- Mesons decay into photons and leptons
• Baryons contains 3 quarks, and antibaryons contain three antiquarks
•All baryons have a baryon number= +-1
•Baryons have lepton number=0
•Baryons have strangeness=0 (do not contain strange quarks)
- Pions contain a quark-antiquark pair
- Has a strangeness of zero ( does not contain any strange quarks )
- π^0 meson can be any combination of a quark and corresponding antiquark.
- Kaons contain a strange quark or antiquark
- They either have an up or down quark or
antiquark, in a quark-antiquark pair.
-
- Leptons are fundamental
- They are not made up of quarks
- They have a lepton number of ± 1
- Leptons are particles and antiparticles that do not interact with the strong interaction.
- Leptons interact through the weak interaction, the gravitational interaction and through the electromagnetic interaction when charged.
Electrons:
- The electron has a charge of -1
- The electron antiparticle is the positron and has a charge of +1
- An electron and neutrino can interact with a neutron to produce a proton and an electron
Muons:
- They have the same negative charge as an electron but 200 times the mass. They are made when high energy cosmic rays collides with atoms in earth's atmosphere. It decays into a electron or a positron
- There must be one electron neutrino and one muon neutrino (antineutrino in the decay)
