Pion-pion scattering analysis of 205 GeV/c pi- p interactions in the NAL 30-inch hydrogen bubble chamber

PDF Version Also Available for Download.

Description

A number of experiments at beam momenta below {approx} 25 GeV/c have yielded results on {pi}{sup -}{pi}{sup +} and {pi}{sup -}{pi}{sup -} scattering cross sections, obtained by modified Chew-Low extrapolation techniques applied to the reactions {pi}{sup -}p {yields} {Delta}{sup 0}{pi}{sup +}{sup -}. They have applied these same techniques to a small sample (169 events) of the reaction {pi}{sup -}p {yields} p{pi}{sup +}{pi}{sup -}{pi}{sup -} obtained from a 48,000-photo exposure of the NAL 30-inch hydrogen bubble chamber to a 205 GeV {pi}{sup -} beam. The statistics are insufficient to test the validity of the analysis at these high energies but they ... continued below

The statistics are insufficient to test the validity of the analysis at these high energies but they find {pi}{sup -}{pi}{sup +} and {pi}{sup -}{pi}{sup -} elastic scattering cross sections in the M{sub {pi}{sup {+-}}{pi}{sup -}} {approx} 3 GeV. Results will be presented of an attempt to obtain inelastic and total {pi}{pi} scattering cross-section estimates under similar assumptions.
