On the quantisation and anomalies of antisymmetric tensor-spinors
arXiv:2109.03963 · doi:10.1007/JHEP11(2021)078
Abstract
We perform the quantisation of antisymmetric tensor-spinors (fermionic -forms) using the Batalin-Vilkovisky field-antifield formalism. Just as for the gravitino (), an extra propagating Nielsen-Kallosh ghost appears in quadratic gauges containing a differential operator. The appearance of this `third ghost' is described within the BV formalism for arbitrary reducible gauge theories. We then use the resulting spectrum of ghosts and the Atiyah-Singer index theorem to compute gravitational anomalies.
