Axial nucleon form factors from lattice QCD
Alexandrou, Constantia; Brinet, M.; Carbonell, J.; Constantinou, Martha; Harraud, P. A.; Guichon, P.; Jansen, K.; Korzec, T.; Papinutto, M. (2011)We present results on the nucleon axial form factors within lattice QCD using two flavors of degenerate twisted mass fermions. Volume effects are examined using simulations at two volumes of spatial length L=2.1fm and ...

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 ...

Low-lying baryon spectrum with two dynamical twisted mass fermions
Alexandrou, Constantia; Baron, R.; Carbonell, J.; Drach, V.; Guichon, P.; Jansen, K.; Korzec, T.; Pène, O. (2009)The masses of the low-lying baryons are evaluated using two degenerate flavors of twisted mass sea quarks corresponding to pseudoscalar masses in the range of about 270-500 MeV. The strange valence quark mass is tuned to ...

Moments of nucleon generalized parton distributions from lattice QCD
Alexandrou, Constantia; Carbonell, J.; Constantinou, Martha; Harraud, P. A.; Guichon, P.; Jansen, K.; Kallidonis, Christos; Korzec, T.; Papinutto, M. (2011)We present results on the lower moments of the nucleon generalized parton distributions within lattice QCD using two dynamical flavors of degenerate twisted mass fermions. Our simulations are performed on lattices with ...
