Lambda baryon


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 a strange (
Λ0
), a charm (
Λ+
c
), a bottom (
Λ0
b
), or a top (
Λ+
t
) 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 one-twentieth the timescale for strong interactions, and therefore it does not form hadrons.
