Renormalization constants for one-derivative fermion operators in twisted mass QCD
C. Alexandrou, M. Constantinou, T. Korzec +2
We present perturbative and non-perturbative results on the renormalization constants of the local and one-derivative vector and axial vector operators. Non-perturbative results ar…
Nucleon Structure in Lattice QCD using twisted mass fermions
C. Alexandrou, M. Constantinou, T Korzec +5
We present results on the nucleon form factors and moments of generalized parton distributions obtained within the twisted mass formulation of lattice QCD. We include a discussion…
A worm-inspired algorithm for the simulation of Abelian gauge theories
Tomasz Korzec, Ulli Wolff
We present an algorithm in which the all-order strong coupling expansion of the Abelian U(1) gauge theory with Wilson plaquette action is sampled. In addition to the vacuum closed…
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…
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…
Electromagnetic form factors of the Delta baryon
Constantia Alexandrou, Tomasz Korzec, Theodoros Leontiou +2
We develop a methodology that enables us to extract accurately the electromagnetic Delta form factors and their momentum dependence. We test our approach in the quenched approximat…
