Pion-Pion Decay Distributions for π⁻p → π⁺π⁻n at 100 and 175 GeV/c


Stampke, Stuart Reh (1982) Pion-Pion Decay Distributions for π⁻p → π⁺π⁻n at 100 and 175 GeV/c. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/bfmr-3581.


We report measurements of the reaction π-p → π+π-n at 100 and 175 GeV/c using a large wire chamber spectrometer at Fermilab. Production of ρ0, f0, and g0 resonances was observed. Cross sections for π-p → π+π-n in the ρ0 mass region are given. Decay angle distributions for ππ masses from .55 to 3.5 GeV/c2 are presented. Moment analyses of the decay distributions are made as a function of ππ mass from .55 to 2.4 GeV/c2. Contours of ππ decay distribution dips are given in sππ and tππ. Comparisons with several lower energy experiments are made. Detailed discussions of the apparatus, trigger, and analysis procedures are given.
