Open strangeness threshold production at COSY-11
P. Winter, H. -H. Adam, A. Budzanowski +21
The open strangeness production near threshold is investigated at the internal experiment COSY-11 in different reaction channels. Recently, the main focus has been to extend measur…
Proposal for the Wide Angle Shower Apparatus (WASA) at COSY-Juelich - "WASA at COSY"
COSY Collaboration, B. Hoistad, J. Ritman
This document describes the physics case, the key experiments proposed and the technical solution for the project "WASA at COSY", which concerns the transfer of the WASA pellet-tar…
Hadronic interaction of the eta meson with two nucleons
P. Moskal, H. -H. Adam, A. Budzanowski +21
The COSY-11 collaboration has conducted experiments aiming at the determination of the excitation function and phase-space population of the p p --> p p eta reaction close to the k…
Transport analysis of K+ production in proton-nucleus reactions
Z. Rudy, W. Cassing, L. Jarczyk +3
The production of mesons in proton-nucleus collisions from 1.0 to 2.3 GeV is analyzed with respect to one-step nucleon-nucleon ) and two-step -nucleon $(ΔN…
New results on the pd --> 3He eta production near threshold
H. -H. Adam, A. Khoukaz, N. Lang +22
Measurements on the eta meson production in proton-deuteron collisions have been performed using the COSY-11 facility at COSY Juelich. Here we present preliminary results on total…

P. Winter, H. -H. Adam, A. Budzanowski +23
The ongoing discussion concerning the nature of the scalar resonances f_0(980) and a_0(980) implicated to extend the studies of the pp -> ppK+K- reaction near the production thresh…
Threshold Hyperon Production at COSY-11
T. Rozek, P. Moskal, H. -H. Adam +23
The Lambda, Sigma0 and Sigma+ hyperon production in NN collisions is studied at the COSY - 11 installation in order to investigate the production mechanism as well as to extract in…
Search for Bremsstrahlung radiation in quasi-free n p --> n p gamma reactions
J. Przerwa, H. -H. Adam, A. Budzanowski +22
Due to the high sensitivity of the N N --> N N gamma reaction to the nucleon-nucleon potential, Bremsstrahlung radiation is used as a tool to investigate details of the nucleon-nuc…
Production of Eta Mesons in Proton-Proton Collisions Close to Threshold
R. Czyzykiewicz, H. -H. Adam, A. Budzanowski +22
A brief experimental overview on the close-to-threshold eta meson production in proton-proton interactions is presented and the available observables in measurements with unpolariz…
Polarization observables in the eta meson production
P. Winter, R. Czyzykiewicz, H. -H. Adam +19
We propose to extend the investigations of the eta meson production in nucleon-nucleon collisions by studying single and double polarization observables. Over the last years, the e…
