Deck model calculation of $pi$$sup -$p $Yields$ $pi$$sup -$$pi$$sup +$$pi$$sup -$p

Description: A Deck-like model for the reaction pi /sup -/p yields pi /sup -/ pi / sup +/ pi /sup -/p is formulated and studied. The model differs from previous Deck calculations in two respects: i) experimental data are used for both pi pi and pi N scattering, and ii) the amplitude has proper Bose symmetry. Feature i) allows one to examine any desired region of 3 pi mass (the A/sub 3/ is treated on the same footing as the A/sub 1/); features i) and ii) allow one to examine all the angular dependence in the… more

Studies of neutron dissociation at FermiLab energies

Description: The characteristics of diffraction dissociation of neutrons into p$pi$$sup -$ systems at high energies were examined. A substantial correlation is observed between the mass and the t of the produced system. The spin structure of the p$pi$$sup -$ amplitudes at low mass is very complex, but is described surprisingly well by the simple Deck Mechanism. Both $pi$-exchange and proton-exchange contributions are evident in diffractive production. The t- channel and s-channel helicity amplitudes contain… more

Unitary coupled channel deck model

Description: A unitary Deck model with coupled K*..pi.. and Krho channels, including only one resonance in the Q region is constructed. Adjusting the resonance parameters, one achieves a satisfactory description of the experimental phase variations and structure in the mass spectra. The resonance is determined to belong to the J/sup PC/ = 1/sup + -/ SU(3) octet, and is thus the Q/sub B/. The relative coupling strength K*..pi../Krho is approximately 2/3.

Diffractive dissociation process. pi. /sup -/p. -->. pi. /sup -/ (. pi. /sup -/. pi. /sup +/p) at 14 GeV/c. [Cross sections, Deck effect, t- and s-channel helicity conservation]

Description: An experiment in which a 14 GeV/c ..pi../sup -/ beam was incident on a hydrogen bubble chamber is described. Fast forward scattered pions traversed a wire spark chamber spectrometer downstream of the bubble chamber. Events identified as inelastic by the spectrometer induced a trigger of the bubble chamber camera. The film produced contained a heavy enrichment of events of proton diffractive dissociation. A sample from this exposure of 4400 events of the reaction ..pi../sup -/p ..-->.. ..pi../su… more
