The transition form factor and the hadronic light-by-light -pole contribution to the muon from lattice QCD
Constantia Alexandrou, Simone Bacchio, Sebastian Burri +11
We calculate the double-virtual transition form factor from first principles using a lattice QCD simulation with $N…
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.…
Nucleon tomography. What can we do better today than Rutherford 100 years ago?
N. G. Stefanis, Constantia Alexandrou, Tanja Horn +2
A survey is presented on the current status of 3D nucleon tomography. Several research frontiers are addressed that dominate modern physics from theory to current and future experi…
Axial charges of hyperons and charmed baryons using twisted mass fermions
C. Alexandrou, K. Hadjiyiannakou, Ch. Kallidonis
The axial couplings of the low lying baryons are evaluated using a total of five ensembles of dynamical twisted mass fermion gauge configurations. The simulations are performed usi…
Direct Evaluation of the Quark Content of Nucleons from Lattice QCD at the Physical Point
A. Abdel-Rehim, C. Alexandrou, M. Constantinou +5
We evaluate the light, strange and charm scalar content of the nucleon using one lattice QCD ensemble generated with two degenerate light quarks with mass fixed to their physical v…
