sentences:  Lambda baryon
  
  The Lambda baryons are a family of subatomic hadron particles containing one up quark, one down quark, and a third quark from a higher flavour generation, in a combination where the quantum wave function changes sign upon the flavour of any two quarks being swapped (thus differing from a Sigma baryon).They are thus baryons, with total isospin of 0, and have either neutral electric charge or the elementary charge +1.
