• Bethe Ansatz and exact form factors of the O(N) Gross Neveu-model 

      Babujian, Hratchya M.; Foerster, Angela; Karowski, Michael (2016) [Artigo de periódico]
      We apply previous results on the O(N) Bethe Ansatz [1{3] to construct a general form factor formula for the O(N) Gross-Neveu model. We examine this formula for several operators, such as the energy momentum, the spin- eld ...
    • The 125 GeV boson : a composite scalar? 

      Doff, A.; Luna, Emerson Gustavo de Souza; Natale, Adriano Antonio (2013) [Artigo de periódico]
      Assuming that the 125 GeV particle observed at the LHC is a composite scalar and responsible for the electroweak gauge symmetry breaking, we consider the possibility that the bound state is generated by a non-Abelian gauge ...
