Sep 12, 2022 · Identify and describe fermions and bosons. Identify and describe the quark and lepton families. Distinguish between particles and antiparticles, and describe their interactions. Elementary particle physics is the study of fundamental particles and their interactions in nature.
What is Particle Physics? Protons, electrons, neutrons, neutrinos and even quarks are often featured in news of scientific discoveries. All of these, and a whole "zoo" of others, are tiny sub-atomic particles too small to be seen even in microscopes. While molecules and atoms are the basic elements of familiar substances that we can see and

Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combination of protons and neutrons is called nuclear physics .
Our best understanding of how these particles and three of the forces are related to each other is encapsulated in the Standard Model of particle physics. Developed in the early 1970s, it has successfully explained almost all experimental results and precisely predicted a wide variety of phenomena.
The theory describes two fundamental types of particles: fermions, which makes up all of the ‘stuff’ around us, and bosons, which mediate how fermions interact with one another. Two familiar examples are the electron (a fermion) and a photon (a boson), the particle of light which carries the electromagnetic force.
The Standard Model of Particle Physics is scientists’ current best theory to describe the most basic building blocks of the universe. It explains how particles called quarks (which make up protons and neutrons) and leptons (which include electrons) make up all known matter.
