Scaling Solutions of Matter Form Factors in Asymptotically Safe Quantum Gravity
Alfio M. Bonanno, Diego Buccio, Emiliano M. Glaviano +1
We investigate the renormalization group flow of a gravity--matter system in which a scalar field is minimally coupled to Einstein gravity and its kinetic term is given by a scale-…
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…
Physical running of couplings in quadratic gravity
Diego Buccio, John F. Donoghue, Gabriel Menezes +1
We argue that the well-known beta functions of quadratic gravity do not correspond to the physical dependence of scattering amplitudes on external momenta, and derive the correct p…
Amplitudes and Renormalization Group Techniques: A Case Study
Diego Buccio, John F. Donoghue, Roberto Percacci
We explore the properties of a simple renormalizable shift symmetric model with a higher derivative kinetic energy and quartic derivative coupling, that can serve as a toy model fo…
Renormalization Group flows between Gaussian Fixed Points
Diego Buccio, Roberto Percacci
A scalar theory can have many Gaussian (free) fixed points, corresponding to Lagrangians of the form . We use the non-perturbative RG to study examples of flows between…
