Abstract:
Elementary particle physics aims at answering fundamental questions such as
Where does the mass of the building blocks of matter come from? What is the dark matter in the universe made of? What is the microscopic structure of space and time? These questions can only be investigated with the help of big accelerators, like the Large Hadron Collider (LHC), which is being built at CERN near Geneva. Moreover, conclusive interpretation of the experimental data will be impossible without precise theoretical predictions of cross sections and other observables. Such predictions can only be obtained from higher order perturbative calculations that require automatization. In this project, we plan to develop computational tools that will be subsequently used to perform large scale computations for key experiments. The focus is on the following topics:
software development, improved prediction of the energy dependence of the electromagnetic coupling, scale and c quark mass dependence in rare B meson decays, precise prediction of the cross section for fermion-anti-fermion scattering, improved prediction of the relation between charged and neutral currents, dependence of the W boson mass and weak mixing angle on the Higgs boson mass.
