Subatomic particles are particles that are smaller than an atom. They include particles such as protons, neutrons, and electrons, as well as other particles like quarks, neutrinos, and bosons. These particles are the building blocks of atoms and play a crucial role in the structure and behavior of matter. Research in this area focuses on understanding the properties, interactions, and behavior of subatomic particles, as well as exploring the fundamental forces that govern their behavior. This research has led to important discoveries in particle physics and has greatly expanded our understanding of the universe at the most fundamental level.
