The v and v nucleon total cross-sections have been determined as a function of energy using a sample of 2500 v and 950 v event. The results are compared with predictions of scaling and charge symmetry hypotheses.

Phys.Rev.Lett. 30 (1973) 1087, 1973.
Inspire Record 83716 DOI 10.17182/hepdata.21415

Cross sections for inelastic scattering of electrons from hydrogen and deuterium were measured for incident energies from 4.5 to 18 GeV, at scattering angles of 18°, 26°, and 34°, and covering a range of squared four-momentum transfers up to 20 (GeVc)2. Neutron cross sections were extracted from the deuterium data using an impulse approximation. Comparisons with the proton measurements show significant differences between the neutron and proton cross sections.

Inclusive single-particle distributions in $\pi^{\pm}$ $p$ reactions at 8 and 16 {GeV/c}

Bosetti, P. ; Grassler, H. ; Kirk, H. ; et al.
Nucl.Phys.B 54 (1973) 141-160, 1973.
Inspire Record 87988 DOI 10.17182/hepdata.811

Invariant single-particle cross sections for pion and proton production in π ± p interactions at 8 and 16 GeV/ c are presented in terms of integrated distributions as functions of x , reduced rapidity ζ and p ⊥ 2 , and also in terms of double differential cross sections E d 2 σ /(d x d p ⊥ 2 ) and d ζ d p ⊥ 2 ). A comparison of π ± and π − induced reactions is made and the energy dependence is discussed. It is shown that the single-particle structure function cannot be factorized in its dependece on transverse and longitudinal momentum. For the beam-unlike pion, there is an indication for factorizability in terms of rapidity and transverse momentum in a small central region.

Inclusive $\pi^-$ Distributions from 205-GeV/c $pp$ Interactions.

Cho, Y. ; Engelmann, R. ; Fields, T. ; et al.
Phys.Rev.Lett. 31 (1973) 413-416, 1973.
Inspire Record 81713 DOI 10.17182/hepdata.21358

Inclusive π− distributions from 205-GeV/c pp interactions, covering the full range of longitudinal and transverse momenta, have been obtained using the 30-in. hydrogen bubble chamber at the National Accelerator Laboratory. These data provide new evidence for scaling in the fragmentation region and for a plateau in the central region of rapidity. The 90°-c.m. invariant cross section varies as exp[−(10±2)PT2] in the range PT2<~0.1 (GeV/c)2.

SEARCH FOR QUARKS AND HEAVY STABLE PARTICLES PRODUCED AT 300-GEV.

Leipuner, L.b. ; Larsen, R.c. ; Sessoms, A.l. ; et al.

Inspire Record 81800 DOI 10.17182/hepdata.21373

We report a search for quasistable particles with anomalous charge or large mass produced by the interaction of 300-GeV protons at the National Accelerator Laboratory. Analyses of energy losses in a counter telescope lead to cross-section limits of 10−35 cm2 for particles with charges of e3 and 2e3 and 5×10−31 cm2 for charge-4e3 particles. Time-of-flight measurements gave cross-section limits of about 10−31 cm2 for the production of massive charged particles.

Characteristics of the Reaction $pp \to p + X$ at 205 GeV/c.

Barish, S.J. ; Colley, D.C. ; Schultz, P.F. ; et al.
Phys.Rev.Lett. 31 (1973) 1080-1083, 1973.
Inspire Record 81790 DOI 10.17182/hepdata.21407

The inelastic reaction p+p→p+X is studied at 205 GeV/c. The distribution of the square of the missing mass, M2, shows a large diffractivelike peak at low M2 due to two-, four-, and six-prong events. The slope of the invariant cross section versus t decreases with increasing M2. The energy dependences of the multiplicity moments for the recoiling system X are similar to those for corresponding moments for p+p→(n chargedparticles).

pp Interactions at 303 GeV/c: Inclusive Studies of Gamma, $K^0_S$, and $\Lambda^0$ Production.

Inspire Record 81780 DOI 10.17182/hepdata.21419

From analysis of V0 events observed in an exposure of the National Accelerator Laboratory 30-in. bubble chamber to 303−GeVc protons, we obtain these results: (1) 〈nπ0〉 rises approximately linearly with n-, implying strong coupling of neutral and charged pions, while 〈nKS0〉 is less coupled to n; (2) γ, KS0, and Λ0 production cross sections are approaching a scaling limit by 303 GeVc; (3) within the limited statistics, dσdy is flat in the central region for KS0 and low-multiplicity γ events.

Momentum spectra for forward Σ− production on beryllium by protons of momentum 25.8 and 29.4 GeVc are presented. Data for the two primary proton momenta are compared for scaling behavior in the invariant cross section. In addition, the observed single-particle momentum distributions are compared with single-particle spectra from other inclusive reactions initiated by protons.

NUCLEAR REACTIONS OF SILVER WITH 300-GEV PROTONS.

English, G. ; Yu, Y.W. ; Porile, N.T. ;
Phys.Rev.Lett. 31 (1973) 244-247, 1973.
Inspire Record 81747 DOI 10.17182/hepdata.21359

Cross sections of 27 radionuclides formed by the interaction of 300-GeV protons with silver were determined on the assumption that the cross section of the reaction Al27(p, 3pn) remains the same as at 10-30 GeV. The results are compared with the corresponding values obtained at 11.5 GeV. The average value of the ratio σ300σ11.5 for all products ranging from Be7 to Ag106m is 0.91±0.07 and is independent of mass number.
