Query: Explicit calculation on two-loop correction to the chiral magnetic
  effect with NJL model   Chiral Magnetic Effect(CME) is usually believed not receiving higher order
corrections due to the non-renormalization of AVV triangle diagram in the
framework of quantum field theory. However, the CME-relevant triangle, which is
obtained by expanding the current-current correlation requires zero momentum on
the axial vertex, is not equivalent to the general AVV triangle when taking the
zero-momentum limit owing to the infrared problem on the axial vertex.
Therefore, it is still significant to check if there exists perturbative higher
order corrections to the current-current correlation. In this paper, we
explicitly calculate the two-loop corrections of CME within NJL model with
Chern-Simons term which ensures a consistent $\mu_5$. The result shows the
two-loop corrections to the CME conductivity are zero, which confirms the
non-renomalization of CME conductivity.
