This first recorded particle is a meson composed of an anti-beauty quark - the beauty quark's antiparticle - and an up quark - one of the two common quarks that make up protons and neutrons.
While up quarks last for billions of years, the large beauty quarks swiftly decay into lower-energy particles in about 1.5 x 10-12 seconds.
By comparing the decay products of beauty quarks, LHC researchers hope to find clues as to why our universe seems to favour matter over antimatter.
