Quaks and Leptons Flashcards
what is a Muon and what is its rest mass compared to an electron
A heavy electron
the rest mass of muon is 200 times the rest mass of electron
what is pion
a particle that can be positive, negative or neutral
has a mass in between muon and proton
it is a meson
what is a kaon
a particle that can be positive, negative, or neutral
has a mass above pion and below proton.
it is a meson
what do hadrons include
baryons and mesons
what are baryons and mesons part of?
hadrons
what are leptons?
leptons are electrons, neutrinos muons
what are electrons, neutrinos and muons part of
