Low Energy Theorems of Quantum Gravity from Effective Field Theory

Journal of Physics G: Nuclear and Particle Physics (2015)

John Donoghue and Barry R. Holstein

In this survey, we review some of the low energy quantum predictions of General Relativity which are independent of details ...

QED trace anomaly, non-local Lagrangians, and quantum Equivalence Principle violations

Journal of High Energy Physics (2015)

John Donoghue and Basem K Mahmoud El-Menoufi

We discuss the derivation of the trace anomaly using a non-local eﬀective action at one loop. Thisprovides a simple and ...

The Equivalence Principle in a Quantum World

International Journal of Modern Physics D (2015)

John Donoghue, N. E. J Bjerrum-Bohr, Basem K Mahmoud El-Menoufi, Barry R Holstein, et al.

We show how modern methods can be applied to quantum gravity at low energy. We testhow quantum corrections challenge the ...

The Equivalence Principle in a Quantum World

N.E.J. Bjerrum-Bohr, John Donoghue, Basem M. El-Menoufi, Barry R Holstein, et al.

We show how modern methods can be applied to quantum gravity at low energy. We test how quantum corrections challenge ...

Non-local quantum effects in cosmology 1: Quantum memory, non-local FLRW ...

Physical Review D (2014)

John Donoghue and Basem K Mahmoud El-Menoufi

We discuss cosmological eﬀects of the quantum loops of massless particles, which lead to temporalnon-localities in the equations of motion ...

On-shell Techniques and Universal Results in Quantum Gravity

Journal of High Energy Physics (2014)

John Donoghue, N. E. J Bjerrum-Bohr and Pierre Vanhove

We compute the leading post-Newtonian and quantum corrections to the Coulomb and Newtonian potentials using the full modern arsenal of ...

Regge behavior in effective field theory

Physical Review D (2014)

John Donoghue, Basem K Mahmoud El-Menoufi and Grigory Ovanesyar

We derive the Regge behavior for the forward scattering amplitude in scalar ﬁeld theory using themethod of regions. We ﬁnd ...

Photon-photon scattering and tests of gauge invariance

Physical Review D (2013)

John Donoghue and Basem K Mahmoud El-Menoufi

We consider the phenomenology of a dimension-four operator that violates electromagnetic gauge invariance. Its magnitude is severely constrained by the ...

On the running of gravitational constant.pdf

Physical Review D (2012)

John Donoghue and Mohamed M. Anber

We show that there is no useful and universal deﬁnition of a running gravitational constant,G(E), in the perturbative regime below ...

Self-healing of unitarity in effective field theories and the onset ...

Physical Review D (2012)

John Donoghue, Mohamed M. Anber and Ufuk Aydemir

In eﬀective ﬁeld theories it is common to identify the onset of new physics with the violation of tree-level unitarity. ...

Running couplings and operator mixing in the gravitational corrections to ...

Physical Review D (2011)

John Donoghue, Mohamed M. Anber and Mohamed El-Houssieny

The use of a running coupling constant in renormalizable theories is well known, but the imple-mentation of this idea for ...

Spatial variation of fundamental couplings and Lunar Laser Ranging

Classical and Quantum Gravity (2011)

Thibault Damour and John Donoghue

If the fundamental constants of nature have a cosmic spatial variation, there will in general be extra forces with a ...

The Emergence of a universal limiting speed

Physical Review D (2011)

John Donoghue and Mohamed M. Anber

We display several examples of how fields with different limiting velocities (the ”speed of light”)at a high energy scale can ...

Breaking diffeomorphism invariance and tests for the emergence of gravity ...

Physical Review D (2010)

John Donoghue, Mohamed M. Anber and Ufuk Aydemir

If general relativity is an emergent phenomenon, there may be small violations of diﬀeomorphism invariance. We propose a phenomenology of ...
