Neil Collins : University of Birmingham MINERVA tool A masterclass tool for students to learn about the ATLAS Experiment at CERN Based on a the ATLAS event display Atlantis Motivates identification of individual particles and events from the signatures seen in the ATLAS detector Project is a joint venture between the Rutherford Appleton Laboratory (RAL) and the University of Birmingham MINERVA is under constant development and we value your feedback! Masterclass INvolving Event Recognition Visualised with Atlantis
Neil Collins : University of Birmingham The Standard Model Higgs boson is a requirement of the Higgs field (Provides a mechanism to give particles mass) • Describes our current understanding of particle physics (How matter is constructed) • Stable matter constructed from first generation particles • Hadrons (including protons and neutrons) are composites of u and d quarks • Protons, neutrons and electrons make up atoms which comprise all stable 'visible' matter • Bosons carry the forces that allow particles to interact
Neil Collins : University of Birmingham The Standard Model
Neil Collins : University of Birmingham ATLAS Physics Program To further our knowledge on how the universe is constructed and works Understand the origin of mass (Higgs and Supersymmetry) Look for physics beyond the standard model (GUT, SUSY, theories of everything) Are quarks and leptons fundamental? Other families of quarks, leptons? Why is there a matter-antimatter asymmetry in the universe? Check production rates of particles, like the W and Z particles
Neil Collins : University of Birmingham ATLAS ATLAS (A Toroidal LHC ApparatuS) is a typical modern detector comprising of a series of layers for particle I.D. and measurement The ATLAS experiment is a collaboration of about 2100 scientists from 167 institutions in 37 different countries.
Neil Collins : University of Birmingham Identifying Events Charged particles leaves tracks due to ionisation Curvature of the track and magnetic field strength gives us the momentum, direction gives us charge Neutral particles leave no tracks Electromagnetic Calorimeter measures the energy of electrons and photons Hadronic calorimeter measures energy of hadrons (protons, neutrons, pions etc.) Particles and events are identified by their detector signatures
