Eta' Mass and Chiral Symmetry Breaking at Large Nc and Nf
Preprint
- 20 March 2001
Abstract
We propose a method for implementing the large-Nc, large-Nf limit of QCD at the effective Lagrangian level. Depending on the value of the ratio Nf/Nc, different patterns of chiral symmetry breaking can arise, leading in particular to different behaviors of the eta-prime mass in the combined large-N limit.Keywords
