From Safeguards Application to Fundamental Physics: Advancements in Reactor Neutrino Detection with the ν-Angra Experiment

E. Kemp, M. P. Albuquerque, J. C. Anjos +10

Operating on a surface with high noise rates and requiring susceptible, yet small-scale detectors, the Neutrinos-Angra detector is an excellent platform for technological developme…

First branching fraction measurement of the suppressed decay $Ξ_{c}^{0} \to π^{-} Λ_{c}^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The $Ξ_{c}^{0}$ baryon is unstable and usually decays into charmless final states by the $c \to s u d$ transition. It can, however, also disintegrate into a $π^{-}$ meson and a…

Testing claims of the GW170817 binary neutron star inspiral affecting $β$ -decay rates

P. A. Breur, J. C. P. Y. Nobelen, L. Baudis +11

On August 17, 2017, the first gravitational wave signal from a binary neutron star inspiral (GW170817) was detected by Advanced LIGO and Advanced VIRGO. Here we present radioactive…
