Gauge dependence of momentum running in higher-derivative gravity
Diego Buccio, Gustavo P. De Brito, Luca Parente
Recent works have argued that improved one-loop beta-functions capturing the physical momentum dependence of one-loop corrected higher-derivative gravity theories are the most suit…

Physical Running in Conformal Gravity and Higher Derivative Scalars
Diego Buccio, Luca Parente, Omar Zanusso
We compute the physical running of a general higher derivative scalar coupled to a nondynamical metric and of higher derivative Weyl invariant gravity with a dynamical metric in fo…

Renormalization and running in the 2D model
Diego Buccio, John F. Donoghue, Gabriel Menezes +1
We calculate the scattering amplitude in the two dimensional model in a regularization scheme independent way. When using cutoff regularization, a new Feynman rule from the…
