Particles and Waves - The Standard Model Flashcards
What is the standard model?
A model of fundamental particles and how they interact
What are the two groups of fundamental particles?
-Fermions
-Bosons
What are fermions?
The particles that make up matter
What are bosons?
Force carrying particles
What does every particle have in the standard model?
An antiparticle
What is the evidence for existence of antimatter?
The production of energy in the annihilation of particles
What is the evidence for existence of quarks?
High energy collisions between electrons and nucleons, carried out in particle accelerators
What is the first evidence for the neutrino?
Beta decay
