A STUDY OF THE REACTION POSITIVE PION-PROTON ---> POSITIVE PION-PROTON PION(0) PION(0) AT 15.7 GEV/C

Unknown Date (has links)
From a sample of 30,400 two prong events the reaction (pi)('+) p (--->) (pi)('+) p (pi)('0) (pi)('0) at 15.7 GeV/c is studied. The data were taken at the SLAC 40'' hybrid bubble chamber with a segmented lead-glass wall placed downstream of the bubble chamber to detect photons and to trigger the bubble chamber upon a deposition of 8 GeV or more of energy. With information from the wall it is possible to reconstruct constrained events with two neutral pions. / The experimental setup and the use of the wall in reconstructing the (pi)('0)'s is described. Invariant masses are presented including the (pi)('0)(pi)('0) mass up to about 4 GeV. No new high mass neutral meson is seen. A van Hove analysis is performed, showing considerable pion diffractive events and production of (DELTA)('++)(1232), f('0)(1270), and (rho)(770). / Events with a (DELTA)('++)(1232) present are isolated and investigated. The cross section for the reaction (pi)('+) p (--->) (DELTA)('++) f('0) (f('0) (--->) (pi)('0)(pi)('0)) is determined to be 25.8 (+OR-) 3.4 microbarns. A moments analysis and amplitude analysis are performed, showing that only S and D wave contributed to the cross section. There is no evidence for the narrow (epsilon)(700), nor for the recently reported f'(1800). / An OPE model calculation is made and compared with data using phase shifts measurements from other experiments. When using phase shifts from Biswas (1981) the model underestimated the cross section below m((pi)('0)(pi)('0)) = 1 GeV, while with phase shifts from Estabrooks and Martin (1974) the model is consistent with the data. / Source: Dissertation Abstracts International, Volume: 44-01, Section: B, page: 0211. / Thesis (Ph.D.)--The Florida State University, 1983.
