THE POSITIVE-PION - NEGATIVE-PION INTERACTION AS STUDIED IN 12 AND 18 GEV PION-NUCLEON REACTIONS

THE POSITIVE-PION - NEGATIVE-PION INTERACTION AS STUDIED IN 12 AND 18 GEV PION-NUCLEON REACTIONS

From a study of peripheral interactions wherein a negative pion of 12 or 18 Gev/c incident on a nucleon produced a pair of high-momentum pions, the pion-pion s-wave interaction was deduced. A pion-pion cross section falling smoothly from 50 mb (300 MeV) to 20 mb (600 MeV) was observed. The forward-b...

Zusammenfassung:From a study of peripheral interactions wherein a negative pion of 12 or 18 Gev/c incident on a nucleon produced a pair of high-momentum pions, the pion-pion s-wave interaction was deduced. A pion-pion cross section falling smoothly from 50 mb (300 MeV) to 20 mb (600 MeV) was observed. The forward-backward assymmetry was negative for low dipion masses. (Author)
