LHCb observes an exceptionally large group of particles

The LHCb experiment at CERN is a hotbed of new and outstanding physics results. In just the last few months, the collaboration has announced the measurement of a very rare particle decay and evidence of a new manifestation of matter-antimatter asymmetry, to name just two examples.

The image above shows the data (black dots) of the reconstructed mass distribution resulting from the combination of the Ξc+ and K- particles. The five particle states are the five narrow peaks standing out from the distribution of data. (Image: LHCb collaboration)


Key experiment at the Large Hadron Collider (LHC) gets upgrade

Large Hadron Collider (LHC)

Scientists are upgrading one of the four main experiments on the world’s biggest atom smasher in hopes it will help them discover previously unknown particles or physical properties.
