Lambda particle is a term used in particle physics to describe a specific particle that is a type of baryon. Synonyms for the term "lambda particle" include the lambda baryon, lambda baryonic state, and Λ. The lambda particle was first discovered in the 1950s and its study has been instrumental in achieving a better understanding of the strong force that governs the interactions between subatomic particles. Other subatomic particles that are related to the lambda particle include the proton and neutron. The study of particle physics and the properties of particles such as the lambda particle is essential to our understanding of the fundamental laws of nature.
