Correlation functions and quantum measures of descendant states
Enrico M. Brehm, Matteo Broccoli
We discuss a computer implementation of a recursive formula to calculate correlation functions of descendant states in two-dimensional CFT. This allows us to obtain any -point f…

Axial gravity and anomalies of fermions
Fiorenzo Bastianelli, Matteo Broccoli
We consider a Dirac fermion in a metric-axial-tensor (MAT) background. By regulating it with Pauli-Villars fields we analyze and compute its full anomaly structure. Appropriate lim…

Weyl fermions in a non-abelian gauge background and trace anomalies
Fiorenzo Bastianelli, Matteo Broccoli
We study the trace and chiral anomalies of Weyl fermions in a non-abelian gauge background in four dimensions. Using a Pauli-Villars regularization we identify the trace anomaly, p…
