Description
The formulation of the glue spin operator and large momentum effective theory will be reviewed and a direct calculation of the glue spin from the lattice calculation with chiral fermion action will be presented. The lattice calculation is carried out with overlap fermion on 2+1 flavor domain wall fermion configurations. Both the overlap and domain wall fermions are chiral fermions. A global fit with large momentum extrapolation on multiple lattices with 4 lattice spacings and one at physical pion mass to assess the systematic errors has been undertaken to reach the final result.
