      Higher representations on the lattice: Perturbative studies 

      Del Debbio, L.; Frandsen, M. T.; Panagopoulos, Haralambos G.; Sannino, F. (2008)
      We present analytical results to guide numerical simulations with Wilson fermions in higher representations of the colour group. The ratio of Λ parameters, the additive renormalization of the fermion mass, and the ...

      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 ...
