Search for Darkonium in $e^+e^-$ Collisions
/ BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

Kernphys.) ; Eberhardt, Klaus (Helmholtz Inst., Mainz ; Mainz U., Inst. Kernphys.) ; Eliav, Ephraim (Tel Aviv U.) et al.
The first ionization potential (IP1) of element 103, lawrencium (Lr), has been successfully determined for the first time by using a newly developed method based on a surface ionization process. The measured IP1 value is 4.9630.080.07 eV. [...]

Development of a He/CdI$_2$ gas-jet system coupled to a surface-ionization type ion-source in JAEA-ISOL: towards determination of the first ionization potential of Lr (Z = 103)
/ Sato, T K (JAEA, Ibaraki) ; Asai, M (JAEA, Ibaraki) ; Sato, N (JAEA, Ibaraki) ; Tsukada, K (JAEA, Ibaraki) ; Toyoshima, A (JAEA, Ibaraki) ; Ooe, K (Niigata U. (main)) ; Miyashita, S (Hiroshima U. (main)) ; Kaneya, Y (JAEA, Ibaraki ; Ibaraki U., Grad. Sch. Sci. Eng.) ; Osa, A (JAEA, Ibaraki) ; Schädel, M (JAEA, Ibaraki) et al.
We report on development of a gas-jet transport system coupled to a surface ionization ion-source in the JAEA-ISOL (Isotope Separator On-Line) system. As a new aerosol material for the gas-jet system, CdI2, which has a low boiling point of 713 °C, is exploited to prevent deposition of the aerosol material on the surface of the ion-source. [...]

Barcelona (main)) ; Re, V (Bergamo U.) ; Bondioli, M ; Bruinsma, M (UC, Irvine (main)) ; Curry, S (UC, Irvine (main)) ; Kirkby, D (UC, Irvine (main)) ; Burke, S (UC, Santa Barbara (main)) ; Callahan, D (UC, Santa Barbara (main)) ; Campagnari, C (UC, Santa Barbara (main)) ; Cunha, A (UC, Santa Barbara (main)) et al.
The silicon vertex tracker at the BABAR experiment is the primary device used in measuring the distance between B0 and meson decay vertices for the extraction of CP asymmetries. It consists of five layers of double-sided, AC-coupled silicon modules, read out by custom integrated circuits. [...]

Measurement of the first ionization potential of lawrencium (element 103)

Kernchem.) ; Eliav, E (Tel Aviv U. (main)) et al.
The chemical properties of an element are primarily governed by the configuration of electrons in the valence shell. Relativistic effects influence the electronic structure of heavy elements in the sixth row of the periodic table, and these effects increase dramatically in the seventh row—including the actinides—even affecting ground-state configurations.

Mu2e Technical Design Report
/ Bartoszek, L ; Barnes, E ; Miller, J P ; Mott, J ; Palladino, A ; Quirk, J ; Roberts, B L ; Crnkovic, J ; Polychronakos, V ; Tishchenko, V et al.
The Mu2e experiment at Fermilab will search for charged lepton flavor violation via the coherent conversion process mu- N --> e- N with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process. [...]
