Inclusive coherent proton diffraction dissociation on helium has been measured in the four-momentum transfer and missing-mass region 0.04<|t|<0.40 (GeV/c)2, MX2<10 GeV2 and for incident proton beam momenta from 46 to 400 GeV/c. We find that the differential cross section d2σdtdMX2 varies slowly with energy, reveals a pronounced peak at MX2≃2 GeV2, and at large masses behaves approximately as 1MX2. The cross section falls exponentially as |t| increases, with a large slope parameter at small momentum transfers and a substantially smaller one at large |t| values, with no clear dip between the two regions as seen in elastic scattering. We compare the experimental t distributions to Glauber-model predictions and find the data provide a sensitive test of the assumptions on the details of the elementary proton diffraction-dissociation amplitudes and on the total cross sections of the diffractively produced states.

The elastic proton-helium differential cross sections have been determined for 5 different incident laboratory energies from 40 to 400 GeV in the range 0.003 < l t I < 0.52 (GeV/c)2. The differential cross section drops 4 - 5 orders of magnitude to the first dip at I t I = 0.22 (GeV/c)2. A Glauber analysis is performed on the data. The inelastic intermediate states are found to be important. The shrinkage of the slope of the differential cross section is measured. The rate of shrinkage is twice as large as in the p-p case. Results on the real part of the elastic scattering amplitude at forward angle and at the dip structure ( l t l similar/equal to 0.22) are presented.

Data on the measurement of the v μ N total cross section at 2–30 GeV are presented. The observed behavior does not contradict a linear dependence on neutrino energy with slope S =0.73 ± 0.08.
Measured charged current total cross section.
Proton-proton and proton-deuteron elastic scattering has been measured for incident laboratory energy from 50 to 400 GeV; minimum |t| values were, for p−p, 0.0005 (GeV/c)2, and for p−d, 0.0008 (GeV/c)2. From the differential cross sections we have determined the ratios of the real to imaginary parts of the forward scattering amplitude, ρpp and ρpd, for p−p and p−d scattering. Using a Glauber approach and a sum-of-exponentials form factor we obtain ρpn for p−n scattering.
