Konferensbidrag (refereegranskat)abstract
- Two-pion production reactions in proton-proton collisions near threshold are measured using an internal cluster-jet hydrogen target and the WASA/PROMICE detector at the CELSIUS storage ring. Four out of the five possible two-pion production reactions are

Tidskriftsartikel (refereegranskat)abstract
- The first measurement of the cross section of the quasifree pn-->pn eta reaction has been carried out at the CELSIUS storage ring using a deuterium internal cluster jet target. The energy dependence of the cross section is extracted using a fixed incident

Tidskriftsartikel (refereegranskat)abstract
- Dibaryons, forbidden by mass to decay into NN pi channel and by quantum numbers into NN channel, may still have escaped detection. In fact, recently an observation of a narrow dibaryon (D) with the mass close to 1920 MeV was reported in the process pp -->

Konferensbidrag (refereegranskat)abstract
- The pp --> pp pi(o) and pn --> pp pi(-) reactions have been measured at 310, 320 and 340 MeV using the CELSIUS proton beam and H-1 and H-2 internal cluster-jet targets. The pi(o) production at 310 MeV has been fully analyzed and a significant deviation fr

Pionic d-wave effects in pp -> pp pi(0) near threshold

Tidskriftsartikel (refereegranskat)abstract
- The angular distribution of neutral pions produced in the pp --> pp pi(0) reaction has been measured at a beam energy of 310 MeV. Significant deviations from isotropy are found, which increase for small excitation energies of the final proton-proton pair.
