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…
The Quark Condensate in Multi-Flavour QCD - Planar Equivalence Confronting Lattice Simulations
Adi Armoni, Mikhail Shifman, Graham Shore +1
Planar equivalence between the large limits of Super Yang-Mills (SYM) theory and a variant of QCD with fermions in the antisymmetric representation is a powerful t…
Gravitational leptogenesis, C, CP and strong equivalence
J. I. McDonald, Graham M. Shore
The origin of matter-antimatter asymmetry is one of the most important outstanding problems at the interface of particle physics and cosmology. Gravitational leptogenesis (baryogen…
The Unbearable Beingness of Light, Dressing and Undressing Photons in Black Hole Spacetimes
Timothy J. Hollowood, Graham M. Shore
Gravitational tidal forces acting on the virtual e+ e- cloud surrounding a photon endow spacetime with a non-trivial refractive index. This has remarkable properties unique to grav…
