      Lattice investigation of the scalar mesons a0(980) and κ using four-quark operators 

      Alexandrou, Constantia; Daldrop, J. O.; Brida, M. D.; Gravina, M.; Scorzato, L.; Urbach, C.; Wagner, M. (2013)
      We carry out an exploratory study of the isospin one a0(980) and the isospin one-half κ scalar mesons using Nf = 2 + 1 + 1 Wilson twisted mass fermions at one lattice spacing. The valence strange quark is included as an ...

      Scalar mesons and tetraquarks by means of lattice QCD 

      Wagner, M.; Alexandrou, Constantia; Gravina, M.; Daldrop, J. O.; Urbach, C.; Brida, M. D.; Scorzato, L.; Wiese, C. (2012)
      We study the light scalar mesons a0(980) and κ using Nf = 2+1+1 flavor lattice QCD. In order to probe the internal structure of these scalar mesons, and in particular to identify, whether a sizeable tetraquark component ...

      Scalar mesons and tetraquarks from twisted mass lattice QCD 

      Wagner, M.; Alexandrou, Constantia; Daldrop, J. O.; Brida, M. D.; Gravina, M.; Scorzato, L.; Urbach, C.; Wiese, C. (2013)
      We study light scalar mesons with particular focus on the a 0(980) using lattice QCD with 2+1+1 dynamical quark flavors. To investigate the structure of these scalar mesons and to identify, whether a sizeable tetraquark ...
