Results on spin-parity analysis of p¯p → π +π -π 0 annihilation at rest from different density hydrogen targets
The results of the spin-parity analysis of the annihilation reaction p¯p → π +π -π 0 at rest are presented. For the first time data from liquid, NTP and low pressure hydrogen are fitted simultaneously. This tecnique allows to disentangle unambiguously the contributions of the different initial atomic states. The results concern the weights of the partial waves, masses and widths of the 0 ++,1 -- and 2 ++ resonances produced in the annihilation.
