Nucleon strange electromagnetic form factors using twisted-mass fermions at the physical point
Constantia Alexandrou, Simone Bacchio, Mathis Bode +7
We present the strange electromagnetic form factors of the nucleon using lattice QCD with twisted mass clover-improved fermions and quark masses tuned to their physical…
Strangeness of nucleons from lattice QCD
Constantia Alexandrou, Simone Bacchio, Mathis Bode +7
We present the strange electromagnetic form factors of the nucleon using lattice QCD simulations with degenerate light, a strange, and a charm quark in the sea with masses tuned to…
Nucleon strange electromagnetic form factors from lattice QCD
Constantia Alexandrou, Simone Bacchio, Mathis Bode +7
We present the nucleon strange electromagnetic form factors using four lattice QCD ensembles with twisted mass clover-improved fermions and quark masses tuned to approx…
Nucleon axial, tensor, and scalar charges and -terms in lattice QCD
Constantia Alexandrou, Simone Bacchio, Jacob Finkenrath +4
We determine the nucleon axial, scalar and tensor charges at the continuum limit by analyzing three twisted mass fermion ensembles with all quark masses tuned to approx…
Nucleon charges and -terms in lattice QCD
C. Alexandrou, S. Bacchio, J. Finkenrath +4
We determine the nucleon axial, scalar and tensor charges and the nucleon -terms using twisted mass fermions. We employ three ensembles with approximately equal physical volume…
