Superrenormalizable quantum gravity with complex ghosts
Leonardo Modesto, Ilya L. Shapiro
We suggest and briefly review a new sort of superrenormalizable models of higher derivative quantum gravity. The higher derivative terms in the action can be introduced in such a w…
Finite Entanglement Entropy of Black Holes
Stefano Giaccari, Leonardo Modesto, Leslaw Rachwal +1
We compute the area term contribution to black holes' entanglement entropy (using the conical technique) for a class of local or weakly non-local super-renormalizable gravitational…
Spectral Dimension from Nonlocal Dynamics on Causal Sets
Alessio Belenchia, Dionigi M. T. Benincasa, Antonino Marciano +1
We investigate the spectral dimension obtained from non-local continuum d'Alembertians derived from causal sets. We find a universal dimensional reduction to 2 dimensions, in all d…
Exact solutions and spacetime singularities in nonlocal gravity
Yao-Dong Li, Leonardo Modesto, Leslaw Rachwal
We give here a list of exact classical solutions of a large class of weakly nonlocal theories of gravity, which are unitary and super-renormalizable (or finite) at quantum level. I…
Finite quantum gauge theories
Leonardo Modesto, Marco Piva, Leslaw Rachwal
We explicitly compute the one-loop exact beta function for a nonlocal extension of the standard gauge theory, in particular Yang-Mills and QED. The theory, made of a weakly nonloca…
Scattering amplitudes in super-renormalizable gravity
Pietro Donà, Stefano Giaccari, Leonardo Modesto +2
We explicitly compute the tree-level on-shell four-graviton amplitudes in four, five and six dimensions for local and weakly nonlocal gravitational theories that are quadratic in b…
Universally Finite Gravitational & Gauge Theories
Leonardo Modesto, Leslaw Rachwal
It is well known that standard gauge theories are renormalizable in D=4 while Einstein gravity is renormalizable in D=2. This is where the research in the field of two derivatives…
