An Isotensor Dibaryon in the $pp \to pp π^{+} π^{-}$ Reaction?

P. Adlarson, W. Augustyniak, W. Bardan +81

Exclusive measurements of the quasi-free $pp \to pp π^{+} π^{-}$ reaction have been carried out at WASA@COSY by means of $p d$ collisions at $T_{p}$ = 1.2 GeV. Total and differential cross…

Spin dependence of η meson production in proton-proton collisions close to threshold

P. Adlarson, W. Augustyniak, W. Bardan +88

Taking advantage of the high acceptance and axial symmetry of the WASA-at-COSY detector, and the high degree of the polarized proton beam of COSY, the reaction pp{\to} ppη has been…

Search for eta-mesic 4He in the dd->3He n pi0 and dd->3He p pi- reactions with the WASA-at-COSY facility

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

The search for 4He-eta bound states was performed with the WASA-at-COSY facility via the measurement of the excitation function for the dd->3He n pi0 and dd->3He p pi- processes. T…

Production and interaction of the eta meson with nucleons and nuclei

Wojciech Krzemien, Oleksandr Khreptak, Paweł Moskal +4

We report on the status of the search for eta-mesic nuclei and the studies of the interaction of the eta meson with nucleons. Recently we have completed the analysis of the new WAS…

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

COSY Collaboration, P. Adlarson, W. Augustyniak +93

Using the production reactions $pd\to {}^3\mbox{He}\,ω$ and $pp \to pp ω$ , the Dalitz plot distribution for the $ω \to π^{+} π^{-} π^{0}$ decay is studied with the WASA detector at COSY, ba…

Search for an Isospin I =3 Dibaryon

P. Adlarson, W. Augustyniak, W. Bardan +91

Various theoretical calculations based on QCD or hadronic interactions predict that in addition to the recently observed dibaryon resonance $d^{*} (2380)$ with $I (J^{P}) = 0 (3^{+})$ there…
