Massless gravitons on a brane from massive gravity in five-dimensional Minkowski space
Basem Kamal El-Menoufi, Lorenzo Sorbo
We discuss the possibility of localizing Einstein gravity on a three-brane embedded in a five-dimensional Minkowski space by giving a space-dependent mass to the graviton. We show…
Regge behavior in effective field theory
John F. Donoghue, Basem Kamal El-Menoufi, Grigory Ovanesyan
We derive the Regge behavior for the forward scattering amplitude in scalar field theory using the method of regions. We find that the leading Regge behavior to all orders can be o…
Non-local quantum effects in cosmology 1: Quantum memory, non-local FLRW equations and singularity avoidance
John F. Donoghue, Basem Kamal El-Menoufi
We discuss cosmological effects of the quantum loops of massless particles, which lead to temporal non-localities in the equations of motion governing the scale factor a(t). For th…
