Partial Wave Analysis of the (pi+ pi+ pi-) System Through the Region of the A3 Meson

Thompson, G. ; Badewitz, R.C. ; Gaidos, J.A. ; et al.
Nucl.Phys.B 69 (1974) 381-398, 1974.
Inspire Record 760 DOI 10.17182/hepdata.32348

A recent spin-parity analysis of the π + π + π − system formed opposite a proton and a coherent deuteron by incident 13 GeV/ c 2 π + mesons, is extended to a three-pion mass of 1.9 GeV/ c . Relative proportions of the contributing partial waves are presented, from threshold, and the A 3 region is discussed in detail. Contrary to results with the (3 π ) − system, a change in phase is noted for the 2 − amplitude decaying to f 0 π + via am S-wave.

Observation of an A3 Amplitude Phase Change

Thompson, G. ; Badewitz, R.C. ; Gaidos, J.A. ; et al.
Phys.Rev.Lett. 32 (1974) 331, 1974.
Inspire Record 772 DOI 10.17182/hepdata.21334

A spin and parity decomposition is presented of the (π+π+π−) final state formed opposite a proton by incident 13-GeV/c π+ mesons. The A3 enhancement is identified as the 2− amplitude decaying to f0π+ via an S wave. A change in relative phase is noted between the 2−S amplitude and the other principal contributions; this is not incompatible with analyses of the (3π)− system. The method employs the University of Illinois three-body partialwave analysis program.
