What do K mesons decay into?
Charged _ mesons, muons and antineutrinos, antimuons, neutrinos
1 of 13
What do _ mesons decay into when charged and not charged?
If charged - decay into neutrinos and antimuons or muons and antineutrinos If no charge - decay into high energy photons
2 of 13
What do muons decay into?
decay into electrons and antineutrinos or positrons and antineutrinos
3 of 13
What classifies as hadrons?
baryons and mesons
4 of 13
What interactions take place for hadrons?
intefere with strong interaction, most decay in week interaction
5 of 13
What do leptons interfere with?
dont interfere with strong, only with the week interaction
6 of 13
What are the 2 branches of leptons?
electron branch and muon branch
7 of 13
What do mesons consist of?
quark antiquark pair
8 of 13
When is and isnt strangeness conserved?
conserved in strong interaction, not conserved in week interaction
9 of 13
What type of meson has a strange particle?
a kaon meson
