Upper limit for the cross section of the overlapping scalar resonances f0(980) and a0(980) produced in proton-proton collisions in the range of the reaction threshold
P. Moskal, H. -H. Adam, A. Budzanowski +26
Utilizing a missing mass technique we investigate the pp --> ppX reaction scanning beam energies in the range permitting to create a mass close to that of the f0(980) and a0(980) s…
Associated strangeness production at threshold
P. Kowina, M. Wolke, H. -H. Adam +22
The associated strangeness dissociation at threshold has been studied at the COSY-11 facility measuring the hyperon - and the K+K- meson pair production. Measurements of the near t…
Strangeness Production in Proton-Proton Collisions Close to Threshold
By M. Wolke, H. -H. Adam, A. Budzanowski +22
Exclusive data on the reactions pp -> ppK+K- and pp -> pK+ Lambda/Sigma0 have been taken at the cooler synchrotron COSY close to threshold. At equal excess energies, an enhancement…
First close-to-threshold measurement of the analyzing power Ay in the reaction p(pol)p -> pp eta
P. Winter, H. -H. Adam, A. Budzanowski +24
At the internal facility COSY-11 a first measurement of the reaction p(pol)p -> pp eta near the production threshold has been performed. Results for the analysing power will be pre…
Kaon Production and Interaction
By M. Wolke, H. -H. Adam, A. Budzanowski +21
Exclusive data on both the elementary kaon and antikaon production channels have been taken at the cooler synchrotron COSY in proton-proton scattering. In the kaon--hyperon product…
