The hadron collider has now discovered 59 new hadrons. These include the tetraquarks most recently discovered, but also new mesons and baryons. All these new particles contain heavy quarks such as “charm” and “bottom”. These hadrons are interesting to study.

What has the LHC discovered?

The Large Hadron Collider (LHC) is also a big hadron discoverer. The atom smasher near Geneva, Switzerland, is most famous for demonstrating the existence of the Higgs boson in 2012, a discovery that slotted into place the final keystone of the current classification of elementary particles.

Is the LHC a failure?

The LHC has failed to reveal, thus far, anything beyond the known particles of the Standard Model. ... All you'd need is a superpartner particle for every one of the Standard Model particles that exists. The Standard Model particles and their supersymmetric counterparts.
