Shockwaves and Time Delays in Einstein-Maxwell Effective Field Theory
Christophe Grojean, Minyuan Jiang, Pham Ngoc Hoa Vuong
We derive the shockwave metric in four-dimensional Einstein-Maxwell effective field theory (EFT) by performing an ultra-relativistic boost of the charged black hole solution accomp…
The seeds of EFT double copy
Quentin Bonnefoy, Gauthier Durieux, Christophe Grojean +2
We explore the double copy of effective field theories (EFTs), in the recently proposed generalized color-kinematics and Kawai-Lewellen-Tye (KLT) approaches. In the former, we syst…
Massive Gravity on a Brane
Z. Chacko, M. Graesser, C. Grojean +1
At present no theory of a massive graviton is known that is consistent with experiments at both long and short distances. The problem is that consistency with long distance experim…
Gravitational Lorentz Violations and Adjustment of the Cosmological Constant in Asymmetrically Warped Spacetimes
Csaba Csaki, Joshua Erlich, Christophe Grojean
We investigate spacetimes in which the speed of light along flat 4D sections varies over the extra dimensions due to different warp factors for the space and the time coordinates (…
Dynamical Instability of Brane Solutions with a Self-Tuning Cosmological Constant
P. Binetruy, J. M. Cline, C. Grojean
A five-dimensional solution to Einstein's equations coupled to a scalar field has been proposed as a partial solution to the cosmological constant problem: the effect of arbitrary…
General Properties of the Self-tuning Domain Wall Approach to the Cosmological Constant Problem
Csaba Csaki, Joshua Erlich, Christophe Grojean +1
We study the dynamics of brane worlds coupled to a scalar field and gravity, and find that self-tuning of the cosmological constant is generic in theories with at most two branes o…
