Particle Physics

There are three types of fundamental particles—leptons, quarks, and carrier particles

Practice this chapter

There are three types of fundamental particles—leptons, quarks, and carrier particles Known particles can be divided into three major groups—leptons, hadrons, and carrier particles (gauge bosons)

Quarks come in six flavors and three colors and occur only in combinations that produce white Hadrons are thought to be composed of quarks, with baryons having three quarks and mesons having a quark and an antiquark

particle physics — the study of and the quest for those truly fundamental particles having no substructure. quark — an elementary particle and fundamental constituent of matter that is a substructure of hadrons. antimatter — matter constructed of antiparticles; antimatter shares most of the same properties of regular matter, with charge being the only difference between many particles and their…. four fundamental forces — gravity, the electromagnetic force, the weak nuclear force, and the strong nuclear force.

Worked example

What does “particle physics” mean in Particle Physics?

  1. 1Use the wording this chapter gives for particle physics.
  2. 2The book says: the study of and the quest for those truly fundamental particles having no substructure.
  3. 3Do not use the meaning of quark. That term means an elementary particle and fundamental constituent of matter that is a substructure of hadrons.

Result: the study of and the quest for those truly fundamental particles having no substructure

Why. That is the meaning this chapter gives for particle physics.

Do not swap particle physics and quark. particle physics means the study of and the quest for those truly fundamental particles having no substructure. quark means an elementary particle and fundamental constituent of matter that is a substructure of hadrons.
