Recursive relations from diffeomorphism in the Randall-Sundrum model

Haiying Cai, Giacomo Cacciapaglia

Models of gravity in warped extra dimensions enjoy invariance under diffeomorphism. We derive the nonlinear transformation rules for the metric perturbations in the unitary gauge. As an off-shell symmetry, the main consequence of diffeomorphism is a set of recursive relations linking consecutive…

Light-by-light scattering: asymptotic expansions, Coulomb resummation and NLO corrections

Ajjath Abdul Hameed, Ekta Chaubey, Hua-Sheng Shao

Light-by-light (LbL) scattering is one of the earliest predictions of quantum electrodynamics (QED). Interest in this process has been renewed following its experimental observation at the LHC and the prospects of future measurements at free-electron laser facilities. In this paper, we refine…

The Two Lives of a Massive Charged Spin-$\tfrac32$ Particle: from Superstrings EFT to Supergravity

Karim Benakli

A charged massive spin-$\tfrac32$ field in a constant electromagnetic background admits two familiar realizations. In supergravity, where it is identified with a gravitino, its mass and charge are tied in Planck units. In the decoupled-gravity regime, the two-derivative Fierz--Pauli system…

history: A tool for fully-differential cross sections at next-to-next-to-leading order

Sven Yannick Klein, Lukas Simon

The software $\texttt{history}$ is designed to calculate fully-differential cross sections for colour-singlet production processes in hadronic collision up to next-to-next-to-leading order in QCD. It is based on the fully-local nested soft-collinear subtraction scheme, whose implementation is…
