Abstract
Proton-antiproton elastic scattering was measured at a centre of mass energy s = 540 GeV. In the four-momentum transfer range 0.21 < −t < 0.50 GeV2 the t-distribution of about 7000 events is well represented by the exponential shape exp (bt) with slope parameter b = 13.7 ± 0.3 GeV−2. A new measurement of the slope for −t < 0.19 GeV2 confirms our earlier result, giving evidence for a change of slope of about 4 GeV−2 around −l̷ ≈ 0.15 GeV2.File in questo prodotto:
