B-type anomaly coefficients for the D3-D7 domain wall

We compute B-type Weyl anomaly coefficients for the two non-supersymmetric codimension-1 domain wall versions of N = 4 super Yang-Mills theory which are holographically dual to the D3-D7 probe-brane system. We compute the two-point function of the (improved) energy-momentum tensor in the presence of the domain wall, to leading order in perturbation theory. From it we determine the two-point function of the corresponding displacement operator and the b2 anomaly coefficient for both domain wall systems.
