The Lambda baryon is a type of subatomic particle classified as a baryon, which means it is made up of three quarks. Specifically, the Lambda baryon consists of one up quark, one down quark, and one strange quark. It is denoted by the symbol Λ and has a mass slightly greater than that of a proton. Lambda baryons are produced in high-energy particle collisions and are important in the study of particle physics. They are unstable and decay into other particles, often involving the emission of a pion or a neutrino. Their properties help scientists understand the strong force that binds quarks together.
