20 Mar 2001 | | Journal: | Phys.Rev.Lett. 86 (2001) 5858-5861 | | Subject: | hep-ph hep-lat | | Affiliation: | Padua U. & INFN), J. Stern and P. Talavera (Orsay, IPN | | 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. | | Source: | arXiv, hep-ph/0103221 | | Services: | Forum | Review | PDF | Favorites | |
