Abstract
We report on measurements of charged pion production cross sections at θ ≅ 50°, p T ≅ 3–9 GeV/ c and √ s = 45 GeV, taken with the Split Field Magnet Detector at the CERN Intersecting Storage Rings (ISR). Together with previous data at √ s = 62 GeV, this allows the calculation of the exponent n assuming a power law dependence p n T. Values of n ≈ 8 are found at low x T = 2 p T/√ s which drop to about 7 at x T ≈ 0.3. The measured values of π +/π − rise with x T and approach ≈ 2 at x T ≈ 0.3. A first-order QCD calculations is reasonably consistent with the data.
