Boundary fermion currents and subleading order chiral anomaly in the AdS/CFT correspondence
Abstract
We construct a wave-functional whose argument couples to boundary fermion currents in the AdS/CFT correspondence. Using this we calculate the contributions from bulk fermions to the chiral anomaly that give the subleading order term in the exact N-dependence of the chiral anomaly of N=4 SYM. The result agrees with the calculation of Bilal & Chu.
