Moments of nucleon generalized parton distributions from lattice QCD simulations at physical pion mass

Understand

We present results for the moments of nucleon isovector vector and axial generalised parton distribution functions computed within lattice QCD.

• Three ensembles of maximally twisted mass clover-improved fermions simulated with a physical value of the pion mass are analyzed.
• Two of these ensembles are generated using two degenerate light quarks.
• A third ensemble is used having, in addition to the light quarks, strange and charm quarks in the sea.
