give detailed information about bozons,hardons and fermions
Answers
Bosons are the particles that follow Bose Einstein Statistics. They have spin integral spins.The name was first coined by Paul Dirac.The interesting fact about bosons is that they have no restriction on the no.of particles that can occupy the same quantum state.They do not obey Pauli exclusion principle. They have symmetric wave functions.e.g, photons, W and Z bosons, gravitons etc.
Fermions are the particles that follow Fermi Dirac Statistics.They obey Pauli exclusion principle and so only one fermion can occupy one quantum state.They have half integral spins.They have antisymmetric wave function.e.g, all quarks and leptons.
Hadrons are the composite particles that are made up of two or more quarks held together by a strong force.They are classified as baryons(made up of odd no.of quarks) and mesons(made up of even no.of quarks).Baryons includes protons as well as neutrons.Mesons includes pions.Most of the mass comes from photons and neutrons.
