Predicting observable parameters that have yet to be measured
All matter is made up of 12 matter particles, 6 quarks and 6 leptons. Their interactions are governed by four forces mediated by the exchange of "force carrier" particles. Hadrons are composite particles made up of multiple quarks held together by gluons, the carrier of the strong force. Hadrons include protons and neutrons, and investigations of difficult-to-observe hadronic properties and strong interactions are the subject of lattice quantum chromodynamics (LQCD). This is the only known mathematical method for investigating hadronic properties without the input of empirical observations and is of growing importance to our predictions about our particle world. The EU-funded multiQCD project is computing challenging time-like hadronic observables through numerical simulations of LQCD.
