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…
