Centrality determination of Au+Au collisions at 1.23A GeV with HADES

HADES collaboration, J. Adamczewski-Musch, O. Arnold +106

The centrality determination for Au+Au collisions at 1.23A GeV, as measured with HADES at the GSI-SIS18, is described. In order to extract collision geometry related quantities, su…

Precision Study of $η^{'} \to γ π^{+} π^{-}$ Decay Dynamics

BESIII Collaboration, M. Ablikim, M. N. Achasov +431

Using a low background data sample of $9.7 \times 1 0^{5}$ $J ψ \to γ η^{'}$ , $η^{'} \to γ π^{+} π^{-}$ events, which are 2 orders of magnitude larger than those from the pr…

Branching fraction measurement of $J / ψ \to K_{S} K_{L}$ and search for $J / ψ \to K_{S} K_{S}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +441

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the BEPCII collider, we study the decays of $J / ψ \to K_{S} K_{L}$ and $K_{S} K_{S}$ . The br…

Deep sub-threshold ϕ production and implications for the K+/K- freeze-out in Au+Au collisions

J. Adamczewski-Musch, O. Arnold, C. Behnke +110

We present data on charged kaons (K+-) and ϕ mesons in Au(1.23A GeV)+Au collisions. It is the first simultaneous measurement of K and ϕ mesons in central heavy-ion collisions below…
