The possibility to determine the pLambda scattering length from the final-state interaction in the reaction pp->pKLambda is investigated experimentally. From a transversely polarized measurement, the K analyzing power (A_N) which, in principle, allows one to extract the spin triplet scattering length is studied. An unexpected energy dependence of the forward/backward symmetric part of A_N is found. The influence of N*-resonances on the pLambda invariant mass spectrum is investigated by exploiting the large acceptance for the process pp->pKLambda->pKppi and is found to be the main source of uncertainty for determining the pLambda scattering length.
Differential cross sections of the reactions $pp to dpi^+$ and $pp to pnpi^+$ have been measured at $T_p = 400$ MeV by detecting the charged ejectiles in the angular range $4^0 leq Theta_{Lab} leq 21^circ$. The deduced total cross sections agree well
It is argued that final state enhancements in production reactions at large momentum transfers, such as pp -> K^+ Lambda p, are primarily sensitive to the position of a virtual bound state pole in the Lambda p system rather than the Lambda p scatteri
This paper reports results from a study of the reaction pp->pK0Sigma+ at beam momenta of p_{beam} = 2950, 3059, and 3200 MeV/c (excess energies of epsilon= 126, 161, and 206 MeV). Total cross sections were determined for all energies; a set of differ
The influence of final-state radiation (FSR) of heavy quarks on observables in high-energy proton-proton collisions is studied. The transverse momentum correlation of D and Dbar mesons, which have been emitted with an azimuthal difference angle close
We are presenting here the new formulae for Bose-Einstein correlations (BEC) which contain effects of final state interactions (FSI) of both strong (in $s$-wave) and electromagnetic origin. We demonstrate the importance of FSI in BEC by analysing dat
