MEASUREMENT OF THE DIFFERENCE IN P P TOTAL CROSS-SECTIONS FOR PURE PARALLEL AND ANTIPARALLEL TRANSVERSE SPIN STATES (DELTA SIGMA (T AT T(P) = 487-MEV, 639-MEV, AND 791-MEV

Ditzler, W.r. ; Hill, D. ; Imai, K. ; et al.
Phys.Rev.D 27 (1983) 680-683, 1983.
Inspire Record 192364 DOI 10.17182/hepdata.23817

The difference between total cross sections in pure transverse-initial-spin states for the p−p interaction has been measured at Tp=487, 639, and 791 MeV, using a frozen-spin target. A comparison with previous data and available phase-shift analyses is made.

SPIN DEPENDENT PARAMETERS P (NOOO), D (NONO), K (NOON), D (SOSO), D (SOKO), M (SOSN), AND M (SOKN) IN P P ELASTIC SCATTERING AT 579-MEV

Aprile, E. ; Hausammann, R. ; Heer, E. ; et al.
Phys.Rev.D 27 (1983) 2600-2616, 1983.
Inspire Record 195612 DOI 10.17182/hepdata.23816

The polarization parameter Pn000, the two-spin parameters Dn0n0, Kn00n, Ds0s0, and Ds0k0, and the three-spin parameters Ms0sn and Ms0kn have been measured for pp elastic scattering at 579 MeV between 34° and 118° center-of-mass scattering angle. The experiment was performed at SIN using a polarized proton beam, a polarized butanol target, and a polarimeter for the measurement of the polarization of the scattered proton. These data form the basis for a complete experimental determination of the scattering amplitudes.

Elastic Scattering of $\pi^{\pm}$ and $K^{\pm}$ on Protons at 100-GeV/c and 200-GeV/c

Kalbach, R.M. ; Krueger, K.W. ; Pifer, A.E. ; et al.
Phys.Rev.D 27 (1983) 2752-2754, 1983.
Inspire Record 195613 DOI 10.17182/hepdata.23833

Data are presented on elastic πp and Kp scattering for values of −t up to 2.5 and 3.5 (GeV/c)2 at incident momenta of 100 and 200 GeV/c, respectively. All of the cross sections are found to be nearly identical, although there is some momentum dependence of the π+p data; a small systematic difference observed between pion and kaon data cannot be explained by geometrical scaling.

CHARACTERISTICS OF NEUTRAL CURRENT INTERACTIONS INDUCED BY NEUTRINOS

Marriner, J. ; Barbaro-Galtieri, A. ; Bosetti, P. ; et al.
Phys.Rev.D 27 (1983) 2569-2579, 1983.
Inspire Record 195608 DOI 10.17182/hepdata.23834

The ratio of neutral-current to charged-current interactions is measured to be 0.30±0.03 for isoscalar targets, in good agreement with the results of previous experiments. Two independent methods are employed for isolating neutral-current events, one based on hadronic interactions, and the other on the momentum transverse to the hadron shower. The ratio of neutral-current interactions on neutrons to those on protons is measured to be 1.08±0.19.

MEASUREMENT OF THE ASYMMETRY PARAMETER A IN PI- P ELASTIC AND CHARGE EXCHANGE SCATTERING AT PION ENERGIES T (PI) = 98-MEV, 238-MEV, 292-MEV, AND 310-MEV

Alder, J.c. ; Joseph, C. ; Perroud, J.p. ; et al.

Inspire Record 192365 DOI 10.17182/hepdata.23839

The asymmetry parameter A in π−p elastic scattering at incident pion laboratory kinetic energies Tπ of 98, 238, and 2922 MeV and in π−p charge-exchange scattering π−p→π0n at Tπ=238, 292, and 310 MeV have been measured over a wide range of scattering angles (typically from about 60° to 130° c.m.) with a polarized proton target. The data have been used in an energy-independent phase-shift analysis to improve the precision of the pion-nucleon phase shifts, to set new limits on violation of isospin conservation in the pion-nucleon S wave, and to confirm significant charge dependence in the P32 wave.

STUDY OF A2 PRODUCTION IN THE REACTION PI- P ---> K0 K- P AT 50-GEV/C, 100-GEV/C, AND 175-GEV/C

Bromberg, C. ; Dickey, J.o. ; Fox, G. ; et al.
Phys.Rev.D 27 (1983) 1-11, 1983.
Inspire Record 191493 DOI 10.17182/hepdata.23901

The reaction π−p→K0K−p has been measured from 50 to 175 GeV/c. The production characteristics of the A2 have been analyzed. We find spin and t dependence similar to lower energies, but the cross section falls rapidly with energy. In a Regge description of π−p→A2−p our data imply a rather small Pomeron-exchange component.

POLARIZATION OF LAMBDA0 HYPERONS IN INCLUSIVE PRODUCTION BY 12-GEV PROTONS ON TUNGSTEN

Abe, F. ; Hara, K. ; Kim, N. ; et al.
Phys.Rev.Lett. 50 (1983) 1102-1105, 1983.
Inspire Record 192461 DOI 10.17182/hepdata.20570

The authors have measured the polarization of 2.4×105 Λ0 hyperons in inclusive production by 12-GeV protons on tungsten at three production angles, 3.5°, 6.5°, and 9.5°. In terms of Feynman's xF and transverse momentum of Λ0, the kinematical range is 0.3<~xF<~0.8 and 0.4<~pT<~1.6 GeV/c. The observed polarization does not depend strongly on xF and increases linearly with pT to 16% at pT=1.0 GeV/c, showing a tendency to level off above that point.

The Reactions $pp \to pp$ $\pi^+ \pi^-, K^+ p \to K^+ p$ $\pi^+ \pi^-$, $\pi^+ p \to \pi^+ p$ $\pi^+ \pi^-$ and $\pi^- p \to \pi^+ \pi^-$ at 147 GeV/c

Inspire Record 194363 DOI 10.17182/hepdata.16321

We have studied the reactionspp→ppπ+π-,K+p→K+pπ+π−π, π+p→ π+,pπ+π− and π−p →π+π− at 147 GeV/c using the 30-inch Fermilab hybrid system. All four reactions were detected with the same apparatus and analyzed in the same way. The energy dependence of the channel cross section was found to beAp−0.6+B for thepp reaction andAp−1+B for the other three. About 90% of the cross section at 147 GeV/c can be accounted for by either beam or target diffraction. Some of the remaining cross section may come from double Pomeron exchange reactions which we tried to isolate. We have tested the hypothesis of a factorizable Pomeron and our data indicates a violation of this hypothesis. We show that the 3π mass enhancement in the mass region 1.2–1.4 GeV is diffractively produced in the π± beam reactions. Fourprong, four-constraint and six-prong, four-constraint cross sections are reported.
