Summary

The elastic scattering of K+ mesons on protons is studied at 3.5 and 5 GeV/c. The total elastic cross-sections are found to be (4.36±0.36) mb and (3.82±0.41) mb respectively. The differential elastic cross-sections, which exhibit characteristic diffraction peaks, are fitted by dσ/dt=(dσ/dt)0e αt , giving α=(3.85±0.12) and (4.70±0.21) (GeV/c)−2 for the two momenta respectively, with |t|⪝0.65 (GeV/c)2. The results are compared to those at neighbouring energies, giving some support to the presence of a real part of the forward scattering amplitude. The diffraction peak shows definite shrinking with increasing momenta. The data are examined in the light of models for high-energy scattering.

Riassunto

Si è studiato lo scattering elastico dei mesoni K+ su protoni a 3.5 e 5 GeV/c. Si trova che le sezioni d'urto elastiche totali sono rispettivamente (4.36±0.36) mb e (3.82±0.41) mb. Le sezioni d'urto elastiche differenziali, che presentano caratteristici picchi di diffrazione, sono approssimate da dσ/dt=(dσ/dt)0e αt , dando α=(3.85±0.12) e (4.70±0.21) (GeV/c)2 rispettivamente per i due impulsi, con |t|⪝0.65 (GeV/c)2. Si confrontano i risultati con quelli ad energie prossime, dando qualche sostegno alla presenza di una parte reale dell'ampiezza di scattering in avanti. Si esaminano i dati alla luce dei modelli dello scattering di alta energia.
