Description:
Author(s): Hiroki Nishihara and Masayasu Harada We study masses and decay widths of positive and negative parity nucleons using a three-flavor parity doublet model, in which we introduce three representations, [ ( 3 , 3 ¯ ) ⊕ ( 3 ¯ , 3 ) ] , [ ( 3 , 6 ) ⊕ ( 6 , 3 ) ] , and [ ( 8 , 1 ) ⊕ ( 1 , 8 ) ] of the chiral U ( 3 ) L × U ( 3 ) R symmetry. We find an extended version of the Goldberger-Treima… [Phys. Rev. D 92, 054022] Published Fri Sep 18, 2015
