Moments of nucleon generalized parton distributions from lattice QCD
C. Alexandrou, J. Carbonell, M. Constantinou +6
We present results on the lower moments of the nucleon generalized parton distri butions within lattice QCD using two dynamical flavors of degenerate twisted mass fermions. Our sim…
Nucleon to Delta transition form factors with domain wall fermions
C. Alexandrou, G. Koutsou, J. W. Negele +2
We calculate the electromagnetic, axial and pseudo-scalar form factors of the Nucleon to transition using two dynamical light degenerate quarks and a dynamical strange qu…
Axial and pseudoscalar form-factors of the Delta^+(1232)
Constantia Alexandrou, Eric B. Gregory, Tomasz Korzec +4
We present first results on the axial and pseudoscalar form factors. The analysis is carried out in the quenched approximation where statistical errors are small and the lattic…
A Study of Hadron Deformation in Lattice QCD
Constantia Alexandrou, Giannis Koutsou
We develop the formalism for the evaluation of density-density correlators in lattice QCD that includes techniques for the computation of the all-to-all propagators involved. A nov…
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…
The nucleon to Delta electromagnetic transition form factors in lattice QCD
C. Alexandrou, G. Koutsou, H. Neff +3
The electromagnetic nucleon to Delta transition form factors are evaluated using two degenerate flavors of dynamical Wilson fermions and using dynamical sea staggered fermions with…
