Measurement of π-p Elastic Scattering at 14.15 GeV/c

Abstract

Results are presented of a wire-spark-chamber spectrometer measurement of the differential cross section for π-p elastic scattering at 14.15 GeV/^c. The region covered in the square of the four-momentum transfer, t, is 0.01<-t<0.78 (GeV/c)^2. The cross section is found to obey very nearly a simple exponential t dependence with no evidence of structure. A fit to the data of the form dσ/dt∝exp(bt+ct2) on the range 0.05<-t<0.78 (GeV/c)^2 (i.e., above the region affected by Coulomb scattering) yields b=8.26±0.10 (GeV/c)^2 and c=1.01±0.17 (GeV/c)^-4. Considering the results of previous measurements, b≃11 (GeV/c)^-2 for -t<0.05 (GeV/c)^2, a deviation from the simple exponential near -t≃0.05 (GeV/c)^2 is indicated.
