Hyperon

n. elementary particle which is relatively massive with greater mass than a nucleon

In particle physics, a hyperon is any subatomic particle which is a baryon (and hence a hadron and a fermion) with non-zero strangeness, but with zero charm and zero bottomness.

Noun
1. any baryon that is not a nucleon; unstable particle with mass greater than a neutron
(hypernym) baryon, heavy particle
(hyponym) lambda particle, lambda hyperon

A sub-set of baryons with masses greater than nucleons (i.e. protons or neutrons) and with extremely short mean lives of, at most, 10-9 second to decay by various modes into lighter particles. They are fermions and are grouped into four subsets of 'fundamental ' particles.
