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…

The hyperfine anomaly in mercury and test of the Moskowitz-Lombardi rule
J. Vandeleur, G. Sanamyan, B. M. Roberts +1
The Moskowitz-Lombardi rule gives a simple relation between the magnetic moment of an atomic nucleus and the effect of its radial distribution on the hyperfine structure - the magn…

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…
