Light baryon masses with dynamical twisted mass fermions
C. Alexandrou, R. Baron, B. Blossier +17
We present results on the mass of the nucleon and the Delta using two dynamical degenerate twisted mass quarks and the tree-level Symanzik improved gauge action. The evaluation is…
Exploring the epsilon regime with twisted mass fermions
K. Jansen, A. Nube, A. Shindler +2
In this proceeding contribution we report on a first study in order to explore the so called epsilon regime with Wilson twisted mass (Wtm) fermions. To show the potential of this a…
Scaling and low energy constants in lattice QCD with N_f=2 maximally twisted Wilson quarks
ETM Collaboration, P. Dimopoulos, R. Frezzotti +3
We report on the scaling of basic hadronic observables in lattice QCD with N_f=2 maximally twisted Wilson dynamical quarks. We give preliminary results for some of the Gasser-Leutw…
Twisted mass fermions: neutral pion masses from disconnected contributions
F. Farchioni, K. Jansen, C. McNeile +12
Twisted mass fermions allow light quarks to be explored but with the consequence that there are mass splittings, such as between the neutral and charged pion. Using a direct calcul…
Comparing iterative methods for overlap and twisted mass fermions
T. Chiarappa, K. Jansen, K. -I. Nagai +6
We present a systematic comparison of various iterative methods to obtain the fermion propagator with both overlap and twisted mass fermions at fixed pion mass in the quenched appr…
