Differential Cross Sections for Neutron-Proton Scattering in the Region of the $d^{*} (2380)$ Dibaryon Resonance

P. Adlarson, W. Augustyniak, W. Bardan +102

Differential cross sections have been extracted from exclusive and kinematically complete high-statistics measurements of quasifree polarized $n p$ scattering performed in the…

Search for $C$ violation in the decay $η \to π^{0} + e^{+} + e^{-}$ with WASA-at-COSY

P. Adlarson, W. Augustyniak, W. Bardan +90

We report on the investigation of the rare decay $η \to π^{0} + e^{+} + e^{-}$ which is of interest to study both $C$ violation in the electromagnetic interaction and to…

Measurement of the $η \to π^{+} π^{-} π^{0}$ Dalitz plot distribution

P. Adlarson, W. Augustyniak, W. Bardan +107

Dalitz plot distribution of the $η \to π^{+} π^{-} π^{0}$ decay is determined using a data sample of $1.2 \cdot 1 0^{7}$ $η$ mesons from $p d \to^{3} He η$ reaction at 1 GeV collected by the…

Search for a dark photon in the $π^{0} \to e^{+} e^{-} γ$ decay

COSY Collaboration, P. Adlarson, W. Augustyniak +113

The presently world largest data sample of pi0 --> gamma e+e- decays containing nearly 5E5 events was collected using the WASA detector at COSY. A search for a dark photon U produc…
