Radion/Dilaton portal freeze-in dark matter in extra-dimensional theories
Amrita Mukherjee, George Sanamyan, Dipan Sengupta
We perform a comprehensive analysis of a radion/dilaton portal freeze-in dark matter in models of stabilized warped extra-dimensions. We show that the relic abundance of a generic…
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…
Electromagnetic moments of the antimony isotopes Sb
S. Lechner, T. Miyagi, Z. Y. Xu +22
Nuclear moments of the antimony isotopes Sb are measured by collinear laser spectroscopy and used to benchmark phenomenological shell-model and \textit{ab initio} calcu…
Empirical determination of the Bohr-Weisskopf effect in cesium and improved tests of precision atomic theory in searches for new physics
G. Sanamyan, B. M. Roberts, J. S. M. Ginges
The finite distribution of the nuclear magnetic moment across the nucleus gives a contribution to the hyperfine structure known as the Bohr-Weisskopf (BW) effect. We have obtained…
