Radion Portal Freeze-Out Dark-Matter

R. Sekhar Chivukula, Joshua A. Gill, Kenn S. Goh +5

We show that, in a consistent model of a stabilized extra-dimensional theory, the radion can serve as a natural portal between ordinary matter and WIMP dark matter. With an effecti…

Limits on Kaluza-Klein Portal Dark Matter Models

R. Sekhar Chivukula, Joshua A. Gill, Kirtimaan A. Mohan +4

We revisit the phenomenology of dark-matter (DM) scenarios within radius-stabilized Randall-Sundrum models. Specifically, we consider models where the dark matter candidates are St…

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…
