Measurements are presented of the inclusive charged-particle cross sections s dσdx for e+e− annihilation at center-of-mass energies of 5.2, 6.5, and 29.0 GeV. Significant scale breaking is observed in these cross sections.

Total cross sections have been measured for the transmission of long-lived neutral K mesons through hydrogen and deuterium. The momentum range for the KL0 was 130-550 MeV/c. The momentum of each detected kaon was measured by time of flight. The cross sections are consistent with earlier less precise results. Comparison of the KL0 cross sections is made with the results of several K-matrix fits to other K¯N data, and the KL0 total cross sections are compared with existing theoretical calculations for K−d total cross sections.
THE AUTHORS ADVISE AGAINST USING THESE CROSS SECTIONS WHEN COMBINING THEM WITH OTHER DATA SETS. IT IS RECOMMENDED THAT ONE SHOULD USE INSTEAD THE ORIGINAL DATA POINTS FOR SINGLE-CHOPPED AND DOUBLE-CHOPPED INJECTION (WHICH HAVE SEPARATE NORMALIZATION ERRORS) FROM WHICH THESE COMBINED DATA ARE DERIVED. A NORMALIZATION ERROR FOR THESE AVERAGED CROSS SECTIONS IS THEREFORE NOT QUOTED.
