Almost two-hundred metres beneath the France-Switzerland border, physicists at CERN’s Large Hadron Collider have observed a new particle. A charming particle. They’ve been on the look-out for him for some time, and now they’ve got him— Xicc++.  

The name doesn’t exactly roll off the tongue, but this guy is more than meets the eye. He’s heavy. He’s charming. He’s a subatomic particle, and he’s a real catch. CERN’s particle smasher— based near Geneva, Switzerland— spotted the fellow during the Large Hadron Collider beauty experiment, or the LHCb experiment for short.

Xicc++ is the elusive brother of the proton, neutron, and of a number of other composite subatomic particles. These particles are all a part of the same family, because they’re all made up of three quarks. What are quarks, you ask? Well, let’s dive in. Continue reading “A Particle Full of Charm”
