Nucleon axial, tensor and scalar charges and -terms in lattice QCD
C. Alexandrou, S. Bacchio, M. Constantinou +4
We determine the nucleon axial, scalar and tensor charges within lattice Quantum Chromodynamics including all contributions from valence and sea quarks. We analyze three gauge ense…
Topological susceptibility from twisted mass fermions using spectral projectors and the gradient flow
Constantia Alexandrou, Andreas Athenodorou, Krzysztof Cichy +5
We compare lattice QCD determinations of topological susceptibility using a gluonic definition from the gradient flow and a fermionic definition from the spectral projector method.…
The nucleon spin and momentum decomposition using lattice QCD simulations
C. Alexandrou, M. Constantinou, K. Hadjiyiannakou +5
We determine within lattice QCD, the nucleon spin carried by valence and sea quarks, and gluons. The calculation is performed using an ensemble of gauge configurations with two deg…
Pion and -meson form factors using four-point functions in N=2 QCD
Constantia Alexandrou, Giannis Koutsou
Hadron wave functions and form factors can be extracted using four-point correlators. Stochastic techniques are used to estimate the all to all propagators, which are required for…
Axial Nucleon and Nucleon to Delta form fractors and the Goldberger-Treiman Relations from Lattice QCD
C. Alexandrou, G. Koutsou, Th. Leontiou +2
We evaluate the nucleon axial form factor, , and induced pseudoscalar form factor, , as well as the pion-nucleon form factor, , in lattice QCD. W…
