Particle Physics

"The study of fundamental particles and forces that constitute matter and radiation."

"The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles)."

"There are three generations of fermions."

"Ordinary matter is made only from the first fermion generation."

"Hadrons that contain an odd number of quarks are called baryons and those that contain an even number are called mesons."

"The proton and the neutron make up most of the mass of ordinary matter."

"The longest-lived mesons last for only a few hundredths of a microsecond."

"Mesons are produced in cyclotrons or other particle accelerators."

"Particles have corresponding antiparticles with the same mass but with opposite electric charges."

"These antiparticles can theoretically form a corresponding form of matter called antimatter."

"Some particles, such as the photon, are their own antiparticle."

"The dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model."

"The reconciliation of gravity to the current particle physics theory is not solved."

"Many theories have addressed this problem, such as loop quantum gravity, string theory, and supersymmetry theory."

"Practical particle physics is the study of these particles in radioactive processes and in particle accelerators."

"Theoretical particle physics is the study of these particles in the context of cosmology and quantum theory."

"The two are closely interrelated."

"The Higgs boson was postulated by theoretical particle physicists and its presence confirmed by practical experiments."

"Particle physics experiments are conducted at the Large Hadron Collider."

"These elementary particles are excitations of the quantum fields that also govern their interactions."
