      Light baryon masses with dynamical twisted mass fermions 

      Alexandrou, Constantia; Baron, R.; Blossier, B.; Brinet, M.; Carbonell, J.; Dimopoulos, Petros; Drach, V.; Farchioni, F.; Frezzotti, R.; Guichon, P.; Herdoiza, G.; Jansen, K.; Korzec, T.; Koutsou, Giannis; Liu, Z.; Michael, C.; Pène, O.; Shindler, A.; Urbach, C.; Wenger, U. (2008)
      We present results on the mass of the nucleon and the Δ using two dynamical degenerate twisted mass quarks and the tree-level Symanzik improved gauge action. The evaluation is performed at four quark masses corresponding ...

      Non-perturbative renormalization of quark bilinear operators with N f = 2 (tmQCD) Wilson fermions and the tree-level improved gauge action 

      Constantinou, Martha G.; Dimopoulos, Petros; Frezzotti, R.; Herdoiza, G.; Jansen, K.; Lubicz, V.; Panagopoulos, Haralambos G.; Rossi, G. C.; Simula, S.; Stylianou, Fotos S.; Vladikas, A. (2010)
      We present results for the renormalization constants of bilinear quark operators obtained by using the tree-level Symanzik improved gauge action and the N f = 2 twisted mass fermion action at maximal twist, which guarantees ...
