The Lambda baryons are a family of subatomic hadron particles
that have the symbols Λ0, Λ+ c, Λ0 b, and Λ+ t and have +1
elementary charge or are neutral. They are baryons containing
three different quarks: one up, one down, and one third quark,
which can be either a strange, a charm, a bottom, or a top
quark. The top Lambda is not expected to be observed as the
Standard Model predicts the mean lifetime of top quarks to be
roughly 5×10^−25 s. This is about 20 times shorter than the
timescale for strong interactions, and therefore it does not
form hadrons. The Lambda baryon Λ0 was first discovered in
October 1950, by V D Hopper and S Biswas of the University of
Melbourne, as a neutral V particle with
