Description
Parton Distribution function can be obtained from calculating
the hadronic tensor on the lattice. It involves a 4-point function evaluation
with two vector or axial-vector currents. We propose to use the source method for
one of the currents and effectively reduce the numerical complexity to that of
a 3-point function. The method can be generalized to evaluate other 4-point functions.
