                      computed using an ensemble of gauge configurations with
                      twisted mass Wilson fermions with masses tuned to
                      approximately reproduce their physical values. A
                      non-perturbative renormalization is carried out for both
                      quark and gluon matrix elements. The contribution of up,
                      down, strange and charm quarks to the proton intrinsic spin,
                      orbital angular momentum and angular momentum are
                      determined. All scale and scheme dependent quantities are
                      given in the $\mathrm{ \overline{MS}}$ scheme at 2~GeV.},
