Scattering amplitudes in the Randall-Sundrum model with brane-localized curvature terms
R. Sekhar Chivukula, Kirtimaan A. Mohan, Dipan Sengupta +2
In this paper we investigate the scattering amplitudes of spin-2 Kaluza-Klein (KK) states in Randall-Sundrum models with brane-localized curvature terms. We show that the presence…
Symmetries, Spin-2 Scattering Amplitudes, and Equivalence theorems in Warped Five-Dimensional Gravitational Theories
R. Sekhar Chivukula, Joshua A. Gill, Kirtimaan A. Mohan +3
Building on work by Hang and He, we show how the residual five-dimensional diffeomorphism symmetries of compactified gravitational theories with a warped extra dimension imply Equi…
Scattering Amplitudes of Massive Spin-2 Kaluza-Klein States with Matter
R. Sekhar Chivukula, Joshua A. Gill, Kirtimaan A. Mohan +3
We perform a comprehensive analysis of the scattering of matter and gravitational Kaluza-Klein (KK) modes in five-dimensional gravity theories. We consider matter localized on a br…
Constraining dark boson decay using neutron stars
Wasif Husain, Dipan Sengupta, A W Thomas
Inspired by the well known anomaly in the life time of the neutron, we investigate its consequences inside neutron stars. We first assess the viability of the neutron decay hypothe…
Graviton-photon production with a massive spin-2 particle
Joshua A. Gill, Dipan Sengupta, Anthony G. Williams
A recent letter Cai et al. [2107.14548] within a phenomenological dark matter framework with a massive graviton in the external state indicated a divergence with increasing centre-…
Spin-2 Kaluza-Klein Scattering in a Stabilized Warped Background
R. Sekhar Chivukula, Dennis Foren, Kirtimaan A. Mohan +2
Scattering amplitudes involving massive spin-2 particles typically grow rapidly with energy. In this paper we demonstrate that the anomalous high-energy growth of the scattering am…
