Two-Pion Production in Proton-Proton Collisions with Polarized Beam
S. Abd El-Bary, S. Abd El-Samad, R. Bilger +46
The two-pion production reaction was measured with a polarized proton beam at 750 and 800 MeV using the short version of the COSY-TOF spectrome…
Polarisation of the omega meson in the pd-->3He+omega reaction at 1360 and 1450 MeV
K. Schonning, Chr. Bargholtz, M. Bashkanov +46
The tensor polarisation of omega mesons produced in the pd-->3He+omega reaction has been studied at two energies near threshold. The 3He nuclei were detected in coincidence with th…
The WASA Detector Facility at CELSIUS
Chr. Bargholtz, M. Bashkanov, M. Berłowski +81
The WASA 4pi multidetector system, aimed at investigating light meson production in light ion collisions and eta meson rare decays at the CELSIUS storage ring in Uppsala is present…
Two-Pion Production in Nucleon-Nucleon Collisions and the ABC-Effect - Approaching a Puzzleby exclusive and Kinematically complete Measurements
T. Skorodko, M. Bashkanov, C. Bargholtz +50
The ABC effect - a puzzling low-mass enhancement in the invariant mass spectrum - is known from inclusive measurements of two-pion production in nuclear collisions, where it a…
Evidence for a 'Narrow' Roper Resonance - the Breathing Mode of the Nucleon
H. Clement, T. Skorodko, M. Bashkanov +43
All the time since its discovery the N(1440) baryon state, commonly known as Roper resonance, has been a state with many question marks - despite of its 4-star ranking in the p…
