Abstract (English)

In this thesis we use lattice QCD to compute scattering phase shifts for elastic twopion scattering in the isospin I = 1 channel. Using Lüscher's formalism, we derive the scattering phase shifts for different total momenta of the two-pion system in a nonrest frame. Furthermore we analyse the symmetries of the non-rest frame lattices and construct 2-pion and rho operators transforming in ...

Translation of the abstract (German)

In dieser Doktorarbeit benutzen wir Gitter QCD um die Streuphasenverschiebungen für elastische 2-pion Streuung im Isospin I=1 Kanal zu berechnen. Mithilfe von Lüschers Formalismus leiten wir die Streuphasen für das 2-pion System mit verschiedenen Gesamtimpulsen her. Ausserdem untersuchen wir die Symmetrien des Gitters im bewegten System und konstruieren 2-pion und rho Operatoren, die sich ...
