A lattice QCD determination of the neutron electric dipole moment at the physical point
Constantia Alexandrou, Andreas Athenodorou, Kyriakos Hadjiannakou +1
Results are presented on the neutron electric dipole moment using an ensemble of twisted mass clover-improved fermions with lattice spacing of fm and phy…
Elastic scattering in the channel
Constantia Alexandrou, Kyriakos Hadjiannakou, Giannis Koutsou +4
We present our study of scattering in the iso-spin channel for the first time at the physical point. The calculation is performed using flavors of twisted…
Topology in high- QCD via staggered spectral projectors
Andreas Athenodorou, Claudio Bonanno, Claudio Bonati +7
We present preliminary lattice results for the topological susceptibility in high- QCD obtained discretizing this observable via spectral projectors on eigenmodes of t…
Determination of the light, strange and charm quark masses using twisted mass fermions
C. Alexandrou, S. Bacchio, G. Bergner +23
We present results for the light, strange and charm quark masses using twisted mass fermion ensembles at three values of the lattice spacing, including two ensembles si…
Quark masses using twisted mass fermion gauge ensembles
C. Alexandrou, S. Bacchio, G. Bergner +24
We present a calculation of the up, down, strange and charm quark masses performed within the lattice QCD framework. We use the twisted mass fermion action and carry out simulation…
P-wave nucleon-pion scattering amplitude in the channel from lattice QCD
Giorgio Silvi, Srijit Paul, Constantia Alexandrou +9
We determine the resonance parameters using lattice QCD and the Lüscher method. The resonance occurs in elastic pion-nucleon scattering with in the isospin $I…
