A new group of particles which have long been hiding in plain sight have finally been discovered thanks to the incredibly sensitive LHCb experiment at CERN.

LHCb, otherwise known as the Large Hadron Collider beauty experiment, is one of seven experiments collecting data at the Large Hadron Collider at CERN. UK participation in the experiment is funded by STFC.

In a paper released today, the LHCb collaboration has announced an exceptional and unique observation of five new baryons, particles composed of three quarks.

Tara Shears, Professor of Physics at University of Liverpool, is Liverpool’s LHCb group lead. She explains why this discovery is significant: "These particles have been hiding in plain sight for years, but it's taken the exquisite sensitivity of LHCb's particle detectors to bring them to our attention.”
