Study of anti-p p ->2pi+2pi- annihilation from S states

The results of the spin-parity analysis of pbar-p -->2pi+2pi-annihilations at very low momentum p (= 50 MeV/c) are reported. (continue

New data on Delta++ baryon productiom in anti-p d annihilation at rest by OBELIX Collaboration

New experimental results on pbar-d annihilation at rest into pions plus a high momentum proton in the final state are discussed. The data sample was collected using the OBELIX spectrometer at the LEAR facility (CERN). The annihilation probabilities, or more precisely the yields (Y) via channels pbar-d -->2pi-pi+pi0p and -->3pi-2pi+pi0p with proton momenta > 400 MeVj have been measured for the first time (continue
