Particle decays are a fundamental aspect of particle physics that involve the transformation of one particle into one or more other particles. This process typically occurs due to the interaction of particles with each other or with external forces. By studying particle decays, scientists can gain insights into the properties of particles, their behavior, and the fundamental forces that govern their interactions. Particle decay processes are important in understanding the structure of matter, the principles of symmetry and conservation laws, and the formation of new particles in high-energy collisions.
