Meson spectroscopy with very low momentum antiprotons

The OBELIX spectrometer, studying at the Low Energy Antiproton Ring (LEAR) of CERN the N̄N annihilation, has collected annihilation data with very low momentum p̄(≈ 50 MeV/c). The results of the spin-parity analysis on the p̄p annihilation into four and five pions are briefly described.
