PARTIAL-WAVE ANALYSIS OF NEUTRAL 3 PI SYSTEM PRODUCED IN REACTIO PI -P-]PI+PI-PI0)N AT 12 AND 15 GEV-C

Abstract:

Data on the charge-exchange reaction π-p → (π+π-π0)n have been taken at beam momenta of 12 and 15 GeV/c, using the CERN Omega Multiparticle Spectrometer. A partial-wave analysis has been made of the (3π)0 system. We observe both natural and unnatural spin-parity production. The natural parity states can be identified with established resonances. In addition a natural spin-parity enhancement is observed at a mass of about 2 GeV/c2 with JP = 4+ preferred. We have called this effect the A2* (203...
