Elementary particles are the basic building blocks of matter and energy in the universe. These particles are subatomic particles that cannot be broken down any further and are the fundamental constituents of all matter. They include particles like electrons, quarks, and neutrinos, as well as force carriers like photons and gluons. Research in the field of elementary particles involves studying the properties and interactions of these particles to understand the fundamental forces that govern the behavior of the universe. This research often involves experiments conducted at high-energy particle accelerators, such as the Large Hadron Collider, to probe the nature of these particles and explore new physics beyond the Standard Model. Overall, the study of elementary particles plays a crucial role in advancing our understanding of the fundamental laws of nature and the origins of the universe.
