Abstract
This paper reports on measurements of the total cross section for the inclusive reaction vμ+N , as a function of incident energy. Neutrinos and antineutrinos with energy in the range 30–300 GeV were produced in the 1982 Fermilab narrow-band neutrino beamline. A total of 35 000 neutrino and 7000 antineutrino interactions were recorded in the CCFR detector located in LabE. The incident neutrino flux was determined by methods similar to those used in previous experiments. The rate of increase with energy of the total cross section (σ/E v) in the range 30 to 75 GeV was determined to be 0.659±0.005(stat)±0.039(syst)×10−38 cm2/GeV and 0.307±0.008(stat)±0.020(syst)×10−38 cm2/GeV for incident neutrinos and antineutrinos, respectively. The 5.9% systematic errors are due primarily to uncertainties in the flux intensity measurement. The energy dependence of the cross section in the regionE ν=100–300 GeV was found to be linear, as determined by relative normalization techniques. A weighted average of our previous and present measurement for the total ν-N cross section yields:

The estimate of the quasielastic cross section was made by integrating the expression for the differential cross section with respect toQ 2, this expression being stated in several articles, for example, T. Kitagaki et al.: Phys. Rev. D28 (1983) 436

Events withE had<0 result from the detector resolution at small values ofE had. Hadronic energy is obtained by summing counter pulse heights. This summation entails a small subtraction of the muon contribution to the shower region. The subtraction, however, dominates the resolution at smallE had, occasionally smearing events to negative values. The resolution function for zeroE had processes was extracted from straight through muons originating in the earth shield upstream of the detector. This resolution function, subsequently, was used to investigate the excess events in the low-y region. For details see, W.K.
