Observation of the charmonium decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +662

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$ is observed. We determine the p…

Evidence for Two Excited $Ω^{-}$ Hyperons

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

Using $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 19,fb $^{- 1}$ collected by the BESIII detector at center-of-mass energies ranging from 4.13 to 4.70,GeV, w…

Observation of $η_{c}$ (1S, 2S) and $χ_{c J}$ decays to 2 $(π^{+} π^{-}) η$ via $ψ$ (3686) radiative transitions

BESIII Collaboration, M. Ablikim, M. N. Achasov +642

Based on $2.7 \times 1 0^{9} ψ (3686)$ decays collected with the BESIII detector, the radiative decay $ψ (3686) \to γ 2 (π^{+} π^{-}) η$ is investigated to measure properties of S- and P…

JUNO Sensitivity to Invisible Decay Modes of Neutrons

JUNO Collaboration, Angel Abusleme, Thomas Adam +651

We explore the decay of bound neutrons into invisible particles (e.g., $n \to 3 ν$ or $nn \to 2 ν$ ) in the JUNO liquid scintillator detector, which do not produce an…

Search for $Δ S = 2$ nonleptonic hyperon decays $Ω^{-} \to Σ^{0} π^{-}$ and $Ω^{-} \to n K^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector at the center-of-mass energy of $s = 3.686$ GeV, we search for the first time for tw…
