Summary
π−p elastic scattering is studied at an incident π− beam momentum of 3.92 GeV/c. From the analysis of about 38 000 elastic events we give the differential cross-section for −t>0.06 (GeV)2. The known structures at −t ≈ 0.8 and 2.8 (GeV)2 are seen. An additional possible structure is present in the backward hemisphere.
Riassunto
Si studia lo scattering elastico π−p ad un impulso del fascio di π− incidente di 3.92 GeV/c. Dall’analisi di circa 38 000 eventi elastici si ottiene la sezione d’urto differenziale per −t>0.06 (GeV)2. Si osservano le note strutture a −t ≈ 0.8 e 2.8 (GeV)2. Un’ulteriore possibile struttura è presente nell’emisfero posteriore.

There is no direct experimental measurement of α for π−p at 4 GeV/c. The value used here was obtained at 3.6 GeV/c. Recent calculations using dispersion relations (5) give a value at 4 GeV/c α ≈ −0.16 with a somewhat smaller error, but are in some disagreement with the measured values at higher energies.
