Flashcards
Quarks,Leptons,And The Big Bang
Cards in this deck (7)
- 1.discovered by Fermi .particles with half-integer spin quantum numbers i.e s=1/2 e.g-electron,proton,neutron.Fermions
- 2.discovered by Satyendra Nath Bose .particles with zero or integer spin quantum number eg.photonBosons
- 3particles on which the "strong force"acts are called hadrons.Hadrons
- 4particles on which "strong force" do not act, "weak force " is the dominent force acting on it.Leptones
- 5.assembly/pair/combination of antiparticles(e.g.positron for electron and antiproton for proton) therfore-positron/antiproton combination is an antimatter.antimatter
- 6.when a particle meet its antiparticle,the two can annihilate each other and their combined energies reappear in another forms. e. g e(-)+e(+)---->y(gamma)+y(gamma). p+p(-)---->4π +4π-.annihilation
