Production of $\pi^+$ and $\pi^-$ at Large Transverse Momentum in pp and pd Collisions at 200, 300, and 400 GeV

Antreasyan, D. ; Cronin, J.W. ; Frisch, Henry J. ; et al.

We have measured the production of π+ and π− in 200-, 300-, and 400-GeV p−p and 400-GeV p−d collisions for transverse momenta (p⊥) ranging from 0.77 to 7.67 GeV/c. At large values of x⊥=2p⊥s, where s is the c.m. energy, we have fitted the p−p data to the form A(1−x⊥)bp⊥−n; we obtain n=8.2±0.5 for π+ and 8.5±0.5 for π−. At x⊥>0.3 the π+π− ratio in p−p collisions rises appreciably with increasing x⊥ whereas the π+π− ratio obtained from the difference of p−d and p−p cross sections is ∼ 1.0 at all x⊥.

Properties of Inclusive Hadron Spectra in Muon Nucleon Scattering at 150-GeV/c

Anderson, H.L. ; Bharadwaj, V.K. ; Booth, N.E. ; et al.

We have studied muon-produced hadrons from a deuterium target. The structure functions and the charge ratios are reported for neutrons; the transverse momentum and azimuthal distributions are reported for deuterons. The structure function for the neutron is similar to that of the proton. The charge ratio of produced hadrons follows the expectation of a simple spin-½ quark model. Transverse-momentum results agree with those at lower energy and are similar to those from hadron-hadron interactions. No azimuthal anisotropy is seen.

Real Part of the Proton-Proton Forward Scattering Amplitude from 50-GeV to 400-GeV.

From measurements of proton-proton elastic scattering at very small momentum transfers where the nuclear and Coulomb amplitudes interfere, we have deduced values of ρ, the ratio of the real to the imaginary forward nuclear amplitude, for energies from 50 to 400 GeV. We find that ρ increases from -0.157 ± 0.012 at 51.5 GeV to +0.039 ± 0.012 at 393 GeV, crossing zero at 280 ± 60 GeV.
