Exact calculation of disconnected loops
C. Alexandrou, D. Christaras, A. O'Cais +1
We present an implementation of the disconnected diagram contributions to quantities such as the flavor-singlet pseudoscalar meson mass which are accelerated by GPGPU technology ut…
Low lying baryon spectrum with dynamical twisted quarks
Vincent Drach, Karl Jansen, Jaume Carbonell +2
We present first results on the octet and decuplet strange baryon spectrum with twisted mass quarks. We use an Osterwalder Seiler valence strange quark with a mass tune…
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…
Strange and charmed baryons using N_f=2 twisted mass QCD
Mauro Papinutto, Jaume Carbonell, Vincent Drach +1
We compute the mass spectrum for strange/charmed baryons in the partially quenched approach using N_f=2 twisted mass QCD configurations. We investigate two main issues: the size of…
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…
Hadron Structure and Form Factors
C. Alexandrou
We review recent results on hadron form factors and nucleon generalized parton distibutions obtained with dynamical lattice QCD simulations. We discuss lattice artifacts and open q…
