Abstract:
The Standard Model of particle physics is an elaborate and highly
successful theory that describes with astonishing accuracy the processes
of the known elementary particles that constitute visible matter.
However, despite its spectacular success, it offers no explanation for
dark matter, nor for other observations such as the baryon asymmetry of
the universe. In this talk I describe several strategies to discover
signals for physics beyond the Standard Model using precision
experiments at low energies. One of the most promising observables is
the anomalous magnetic moment of the muon. In order to provide a
stringent test of the validity of the Standard Model the effects of the
strong interaction must be controlled with high precision. I discuss
recent efforts to reduce hadronic uncertainties substantially using
lattice Quantum Chromodynamics.
