Complementary Time- and Distance-Based Methods for Cosmogenic $^{9}$ Li/ $^{8}$ He Background Estimation

Cailian Jiang, Qishan Liu, Liangjian Wen +4

Cosmogenic $^{9}$ Li and $^{8}$ He isotopes constitute an important correlated background in low-energy neutrino experiments because their $β$ -delayed neutron decay signatures can mi…

Observation of $η (2600)$ and Threshold Enhancements in the $Λ Λ ˉ$ System

BESIII Collaboration, M. Ablikim, M. N. Achasov +716

Using $2712.4 \pm 14.3$ million $ψ (3686)$ events collected with the BESIII detector, the $Λ Λ ˉ$ system produced in $ψ (3686)$ radiative decays is studied. A model-independent part…
