Large Hadron Collider teams find new three exotic particles
The Large Hadron Collider beauty (LHCb) team discovered three new kinds of exotic particles: a pentaquark, double-charged tetraquark, and neutral tetraquark.
The pentaquark is made up of a charm quark, anti charm quark, an up, a down, and a strange quark. The pentaquark has been observed before but this is the first pentaquark that contains a strange quark. The doubly electrically charged tetraquark consists of a charm, a strange antiquark, an up quark, and a down antiquark, and the third one is its neutral counterpart of the doubly electrically charged.
Quarks are fundamental particles that made up matter. All the matter around is made up of protons and neutrons and all of these are composed of quarks. They come in six flavors: up, down, charm, strange, top, and bottom. The proton is composed of two up quarks and one down quark, while neutrons contain two down quarks and an up quark. Any particles that consist of quarks and experience strong nuclear force are called Hadrons. The particles that contain more than three quarks are called exotic hadrons.
