Flashcards
Astrophysics - Fundamental particles
Cards in this deck (8)
- 1Which particles don't have antiparticles?Photons and Mesons
- 2How many types of fundamental particles are there? What are they?There are 3 types of fundamental particles. They are:
a) Field particles
b) Leptons
c) Hadrons - 3Field particles consist.....Photons, bosons and gravitons.
Photons carry EM waves,
Bosons carry weak nuclear forces and
Gravitons carry gravitational force. - 4Leptons include........Electrons, Muons and Tau
- 51. Leptons take part in..... 2. Leptons have spins and lifespan of.......1. EM and weak nuclear reactions.
2. spin = 1/2, lifespan = infinite. - 6Hadrons include......Mesons and Baryons.
- 71. Hadrons take part in...... 2. Mesons have spin of..... 3. Baryons have spin of....1. Strong nuclear reactions
2. spin of meson is 0.
3. spin of baryon is not zero. - 8Comparison between antiparticles and particles.Antiparticles have the same mass and spin but equal and opposite charge, baryon number and lepton number.
