Abstract (English)

We present the results of a systematic, first-principles study of the spectrum and decay constants of mesons for different numbers of color charges N, via lattice computations. We discuss the extrapolations to the chiral, continuum and large-N limits and present a comparison of our results to some of the numerical computations and analytical predictions available in the literature.

Translation of the abstract (German)

Wir präsentieren die Ergebnisse einer systematischen, ab initio Studie des Meson-Spektrums und der -Zerfallskonstanten für unterschiedliche Zahlen von Farbladungen N unter Vervwendung von Gittersimulation. Wir diskutieren die Extrapolation zum chiralen, zum Kontinuums- und Large-N Limes und vergleichen unsere Ergebnisse mit einigen der numerischen Berechnungen und analytischen Vorhersagen der Literatur.
