Interrogating the composition and distribution of nuclear magnetization via the hyperfine anomaly: experiment meets nuclear and atomic theory for short-lived K
M. L. Bissell, M. Jankowski, A. Antušek +22
To date, the magnetic structure of nuclei has been poorly constrained, with limited information on its spatial distribution. In this work, we address the composition and distributi…
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…
Smallness of the nuclear polarization effect in the hyperfine structure of heavy muonic atoms as a stimulus for next-generation experiments
J. Vandeleur, G. Sanamyan, O. R. Smits +3
There is renewed interest in studies of muonic atoms, which may provide detailed information on nuclear structure. A major limiting factor in the interpretation of measurements is…
