Weyl anomaly of conformal higher spins on six-sphere
Abstract
This paper is a sequel to arXiv:1309.0785 were we computed the Weyl anomaly a-coefficient on d-sphere for higher-derivative conformal higher spin field in d=4 and shown that it matches the expression found in arXiv:1306.5242 by a "holographic" method from a ratio of massless higher spin determinants in AdS5. Here we repeat the same computation on 6-sphere and demonstrate that the result agrees again with the one following from AdS7. We also discuss explicitly similar matching in the d=2 case.
