Measurement of Differential Cross-Sections for anti-Proton-Proton Annihilation Into Charged Pion and Kaon Pairs Between 0.79-GeV/c and 2.43-GeV/c

Inspire Record 99060 DOI 10.17182/hepdata.31972

Differential cross sections have been measured for the interactions p p → π − π + and p p → K − K + over a centre of mass angular range −0.95 ⩽ cos θ ∗ ⩽ 0.95 at 20 incident momenta between 0.79 and 2.43 GeV/ c . A magnetic spectrometer with wire spark chambers was used. Typically 2000 π − π + and 300 K − K + events were obtained at each momentum. Results are compared with those from related experiments.

Anti-Proton-Proton Annihilation Into pi+ pi- and K+ K- at 6.2-GeV/c

Buran, T. ; Eide, A. ; Helgaker, P. ; et al.
Nucl.Phys. B116 (1976) 51-64, 1976.
Inspire Record 110027 DOI 10.17182/hepdata.35565

The angular distributions for the two annihilation channels p ̄ p →π + π − and p ̄ p → K + K − have been measured at 6.2 GeV/ c . The two-pion channel shows peripheral peaks for π + and π − going forward, and the two-kaon channel shows a peripheral peak for the K − going forward. The results have been compared with the line-reversed elastic backward scattering reactions and also with a constituent interchange model.
