The matter we see today is made up of quarks. Quarks and anti-quarks fit together to make other particles such as mesons which are made up of a quark and an anti-quark pair and baryons that are made from three quarks. Recent studies show that there are other particles that are not mesons or baryons. We search structures that have two quarks and two anti-quarks using the data collected at CERN, which can provide a deeper understanding for how nature works.
