Search for $τ^{-} \to μ^{-} μ^{+} μ^{-}$ decays at the LHCb experiment with Run 2 data

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1188

A search for the lepton-flavour-violating decay $τ^{-} \to μ^{-} μ^{+} μ^{-}$ is carried out using data collected by the LHCb experiment between 2016 and 2018 in proton-proton collisions at t…

Probing super-heavy dark matter with ultra-high-energy gamma rays

Marco Chianese, Ninetta Saviano, Sara Cesare +4

We refine the constraints on the lifetime of decaying super-heavy dark matter particles (SHDM), with masses ranging from $1 0^{7}$ to $1 0^{15}$ GeV, by analyzing ultra-high-energy (UH…
