Particle physics

a branch of physics that focuses on the study of the most fundamental particles that make up matter and the forces acting upon them. These particles include quarks, electrons, neutrinos, photons, and other subatomic particles. It also investigates the interactions between these particles, such as gravity or electromagnetism. In summary, particle physics studies the fundamental particles that make up all matter, while nuclear physics focuses on the particles within atomic nuclei and their interactions.
