Abstract

Abstract The divergences coming from a particular sector of gravitational fluctuations around a generic background in general theories of quadratic gravity are analyzed. They can be summarized in a particular type of scalar model, whose properties are discussed. We analyze in particular with some care arguments against this particular scalar model being unitary. We also discussed the product anomaly in this context.
