    • A chiral bag model with a soft surface : structure and solutions of the fuzzy and the modified fuzzy bag model 

      Vasconcellos, Cesar Augusto Zen; Coelho, Hélio Teixeira; Pilotto, Fernando Goncalves; Bodmann, Bardo Ernst Josef; Dillig, Manfred; Razeira, Moises (1998) [Journal article]
      In the present work we propose a new bag model for hadrons, called the modi ed fuzzy bag model (MFBM). The distinguishing feature of this model is the suppression of the pion eld, as it enters the bag, by means of a scalar ...

    • Exact form factors of the SU(N) Gross–Neveu model and 1/N expansion 

      Babujian, Hratchya M.; Foerster, Angela; Karowski, Michael (2010) [Journal article]
      The general SU(N) form factor formula is constructed. Exact form factors for the field, the energy–momentum and the current operators are derived and compared with the 1/N-expansion of the chiral Gross–Neveu model and full ...
