      Importance of closed quark loops for lattice QCD studies of tetraquarks 

      Berlin, J.; Abdel-Rehim, A.; Alexandrou, Constantia; Brida, M. D.; Finkenrath, J.; Gravina, M.; Leontiou, Theodoros; Wagner, M. (Proceedings of Science (PoS), 2016)
      To investigate the light scalar tetraquark candidate a0(980) (quantum numbers JP =0+), a correlation matrix including a variety of two- and four-quark interpolating operators has to be computed. We discuss efficient ...

      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 ...
