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…
Vector-Like Top Quark Production via an Electroweak Dipole Moment at a Muon Collider
Alexander Belyaev, R. Sekhar Chivukula, Benjamin Fuks +2
Vectorial partners of the Standard Model quarks and leptons are predicted in many dynamical models of electroweak symmetry breaking. The most easily accessible of these new particl…
