Surfin' pp-waves with Good Vibrations: Causality in the presence of stacked shockwaves
Calvin Y. -R. Chen, Claudia de Rham, Aoibheann Margalit +1
Relativistic causality constrains the -matrix both through its analyticity, and by imposing lower bounds on the scattering time delay. These bounds are easiest to determine for…
Positivity-causality competition: a road to ultimate EFT consistency constraints
Mariana Carrillo González, Claudia de Rham, Sumer Jaitly +2
Effective field theories (EFT) are strongly constrained by fundamental principles such as unitarity, locality, causality, and Lorentz invariance. In this paper, we consider the EFT…
To Half--Be or Not To Be?
Claudia de Rham, Sebastian Garcia-Saenz, Lavinia Heisenberg +2
It has recently been argued that half degrees of freedom could emerge in Lorentz and parity invariant field theories, using a non-linear Proca field theory dubbed Proca-Nuevo as a…
A dynamical formulation of ghost-free massive gravity
Claudia de Rham, Jan Kożuszek, Andrew J. Tolley +1
We present a formulation of ghost-free massive gravity with flat reference metric that exhibits the full non-linear constraint algebraically, in a way that can be directly implemen…
