    Experimental Particle Physics

     

    Particle Physics is the science that tries to understand what the most elementary constituents of matter are and to deduce the laws of nature that govern their interactions. The Standard Model of particle physics provides an astonishingly good description of the fundamental particles and their interactions. The electroweak sector is beautifully and precisely calculable from photon exchange in QED with the addition of the gauge bosons W and Z to mediate the weak interaction. The strong interaction sector is described remarkably well at high energies by QCD. Many physicists, however, believe that the Standard Model must be incomplete since so many parameters, including the quark and lepton masses, the quark mixing angles, and the nature of the Higgs sector, are not calculable but instead must be inserted by hand. In addition recent results from astrophysics indicate that 95% of the content of the universe has not been identified.


    Physics beyond the Standard Model, such as supersymmetry, grand unification, and superstrings, promises to enable calculation of many of these parameters from fundamental principles. New phenomena predicted in the mass range to be made accessible at the LHC includes a complete elucidation of the Higgs sector and the likely discovery of many new particles - the super-partners of the Standard Model quarks, leptons, and gauge bosons. These potential discoveries, and more probably those yet to be imagined, will most likely occur at a hadron collider with a detector that emphasizes high quality lepton detection. Such a detector is the one designed for use at the LHC: the Compact Muon Solenoid (CMS) detector.
