Precision spectroscopy and laser-cooling scheme of a radium-containing molecule
/ Udrescu, S M (MIT) ; Wilkins, S G (MIT) ; Breier, A A (Kassel U.) ; Athanasakis-Kaklamanakis, M (CERN ; Leuven U.) ; Ruiz, R F Garcia (MIT) ; Au, M (CERN ; Mainz U.) ; Belošević, I (TRIUMF) ; Berger, R (Philipps U. Marburg) ; Bissell, M L (Manchester U.) ; Binnersley, C L (Manchester U.) et al.
Molecules containing heavy radioactive nuclei are predicted to be extremely sensitive to violations of the fundamental symmetries of nature. The nuclear octupole deformation of certain radium isotopes massively boosts the sensitivity of radium monofluoride molecules to symmetry-violating nuclear properties. [...]

Opportunities for Fundamental Physics Research with Radioactive Molecules
/ Arrowsmith-Kron, Gordon (Michigan State U.) ; Athanasakis-Kaklamanakis, Michail (CERN ; Leuven U.) ; Au, Mia (CERN ; Mainz U.) ; Ballof, Jochen (CERN ; Michigan State U.) ; Berger, Robert (Philipps U. Marburg) ; Borschevsky, Anastasia (U. Groningen, VSI) ; Breier, Alexander A. (Kassel U.) ; Buchinger, Fritz (McGill U.) ; Budker, Dmitry (Darmstadt, GSI ; UC, Berkeley) ; Caldwell, Luke (JILA, Boulder ; U. Colorado, Boulder ; Colorado U.) et al.
Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei.

Isotope Shifts of Radium Monofluoride Molecules
/ Udrescu, S.M. (MIT) ; Brinson, A.J. (MIT) ; Ruiz, R.F. Garcia (MIT ; CERN) ; Gaul, K. (Philipps U. Marburg) ; Berger, R. (Philipps U. Marburg) ; Billowes, J. (Manchester U.) ; Binnersley, C.L. (Manchester U.) ; Bissell, M.L. (Manchester U.) ; Breier, A.A. (Kassel U.) ; Chrysalidis, K. (CERN) et al.
Isotope shifts of $^{223-226,228}$Ra$^{19}$F were measured for different vibrational levels in the electronic transition $A^{2}{}{\Pi}_{1/2}\leftarrow X^{2}{}{\Sigma}^{+}$. The observed isotope shifts demonstrate the particularly high sensitivity of radium monofluoride to nuclear size effects, offering a stringent test of models describing the electronic density within the radium nucleus.

(SLAC) et al.
A new paradigm for data-driven, model-agnostic new physics searches at colliders is emerging, and aims to leverage recent breakthroughs in anomaly detection and machine learning. In order to develop and benchmark new anomaly detection methods within this framework, it is essential to have standard datasets. [...]
