Causality, Renormalizability and Ultra-High Energy Gravitational Scattering
Timothy J. Hollowood, Graham M. Shore
The amplitude A(s,t) for ultra-high energy scattering can be found in the leading eikonal approximation by considering propagation in an Aichelburg-Sexl gravitational shockwave bac…

Causality Violation, Gravitational Shockwaves and UV Completion
Timothy J. Hollowood, Graham M. Shore
The effective actions describing the low-energy dynamics of QFTs involving gravity generically exhibit causality violations. These may take the form of superluminal propagation or…

The c and a-theorems and the Local Renormalisation Group
Graham M. Shore
The Zamolodchikov c-theorem has led to important new insights in our understanding of the renormalisation group and the geometry of the space of QFTs. Here, we review the parallel…
