Spin and momentum fraction carried by partons in the nucleon
Constantia Alexandrou, Simone Bacchio, Jacob Finkenrath +6
We determine the momentum fraction and angular momentum carried by quarks and gluons in the proton in lattice QCD. We use four ensembles simulated with up, down, strange and charm…
Nucleon unpolarized second Mellin moments using lattice QCD ensembles with physical quark masses and in the continuum limit
Constantia Alexandrou, Simone Bacchio, Jacob Finkenrath +6
We compute the matrix elements of the energy-momentum tensor of the nucleon using four ensembles of twisted mass clover-improved fermions with the up, down, strange and charm quark…
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…
Quark and gluon momentum fractions in the pion and in the kaon
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +9
We present results on the momentum fraction carried by quarks and gluons in the pion and the kaon. We employ three gauge ensembles generated with Wilson twisted-mass cl…
