Abstract (English)

In this thesis we address several topics of lattice QCD. As a first project we perform calculations of ground and excited states of light mesons. Especially the extraction of the excited states turns out be very difficult. Therefore we utilize the variational method, which requires the construction of a rich basis of different interpolating fields, i.e., lattice discretized operators which have ...

Insbesondere die Extraktion von angeregten Zuständen gestaltet sich sehr schwierig. Deshalb verwenden wir die Variationsmethode, welche es jedoch erforderlich macht, eine reichhaltige Basis von verschiedenen Interpolatoren, also ...
