We present the second order contributions to the coefficient functions for the parity violating polarized structure functions gL and g4, thus completing the O(αS2) knowledge on DIS structure functions. We obtain the missing O(αS2) pieces from the known parity conserving unpolarized coefficient functions. We also present a phenomenological analysis for the phase space region the future Electron-Ion Collider is set to explore.

Abstract
We present the second order contributions to the coefficient functions for the parity violating polarized structure functions gL and g4, thus completing the O(αS2) knowledge on DIS structure functions. We obtain the missing O(αS2) pieces from the known parity conserving unpolarized coefficient functions. We also present a phenomenological analysis for the phase space region the future Electron-Ion Collider is set to explore.
