LEADING PROTON AND ANTI-PROTON DISTRIBUTIONS IN PROTON NUCLEUS AND ANTI-PROTON NUCLEUS INTERACTIONS

Bailey, R. ; Blanar, G. ; Bosman, M. ; et al.
Z.Phys.C 29 (1985) 1-8, 1985.
Inspire Record 221966 DOI 10.17182/hepdata.15989

We present a study of leading protons and antiprotons inp-nucleus and\(\bar p\)-nucleus on Be, Cu, Ag, W, and U targets. The experiment was performed at the CERN-SPS at a beam energy of 120 GeV. For all targets a suppression of secondary antiprotons with respect to protons is observed. The difference between the\(\bar p\) andp spectra increases with decreasing χ-values and the effect is stronger for heavier nuclei. The features of the data are qualitatively consistent with multiple-collisions modesls. The data are analysed in terms of a dual parton model which gives a satisfactory description of leadingp and\(\bar p\) spectra.

DIFFERENCES BETWEEN PROTON AND PI- INDUCED PRODUCTION OF THE CHARMONIUM CHI STATES

Bauer, Daniel A. ; Graff, T.L. ; Lukens, P.T. ; et al.
Phys.Rev.Lett. 54 (1985) 753-756, 1985.
Inspire Record 216287 DOI 10.17182/hepdata.20333

The charmonium χ states are observed in both π− and p Be interactions near 200 GeV/c via their radiative decay into J/ψ. The χ(3510) and χ(3555) are produced with roughly equal cross sections in π− collisions while the χ(3555) dominates in p collisions. Simple gluon fusion can account for χ production with incident protons but additional mechanisms are needed for incident π−.

The masses, total widths, and leptonic widths of three triplet s-wave bb¯ states ϒ(4S), ϒ(5S), and ϒ(6S) are determined from measurements of the e+e− annihilation cross section into hadrons for 10.55

INCLUSIVE PRODUCTION OF OMEGA- AND ANTI-OMEGA+ BY K0(L) CARBON INTERACTIONS IN THE ENERGY RANGE 80-GEV/C - 280-GEV/C

Hartouni, Edward P. ; Atiya, M.S. ; Holmes, Stephen D. ; et al.
Phys.Rev.Lett. 54 (1985) 628-630, 1985.
Inspire Record 216075 DOI 10.17182/hepdata.20341

We have measured the total cross sections of Ω− and Ω¯+ forward (xF>~0) inclusive production in KL0-carbon interactions in the range EK0=80 to 280 GeV to be 3.5±1.4 and 2.4±1.0 μb, respectively. We observe that the xF distributions for both of these states are increasing from xF=0 to xF≈0.6. The p⊥2 distributions are described as an exponential function in p⊥ with an average p⊥2 of 0.540 GeV2/c2.

EXCLUSIVE PRODUCTION OF K+ K- pi+ pi- IN PHOTON-PHOTON COLLISIONS

The TPC/Two Gamma collaboration Aihara, H. ; Alston-Garnjost, M. ; Armitage, J.C. ; et al.
Phys.Rev.Lett. 54 (1985) 2564, 1985.
Inspire Record 213402 DOI 10.17182/hepdata.20345

We report a measurement of the reaction γγ→K+K−π+π− in both tagged and untagged events at PEP. The cross section rises with invariant γγ mass to about 15 nb at 2 GeV and falls slowly at higher masses. We find clear evidence for the processes γγ→φπ+π− and γγ→K*0(892)Kπ. Upper limits (95% C.L.) of 1.5 and 5.7 nb in the mass range from 1.7 to 3.7 GeV are obtained for φρ0 and K*0K¯*0 production, respectively.

A Measurement of $\bar{p} p$ and $p p$ Elastic Scattering in the Dip Region at $\sqrt{s}=53$-{GeV}

Breakstone, A. ; Crawley, H.B. ; Dallavalle, G.M. ; et al.
Phys.Rev.Lett. 54 (1985) 2180, 1985.
Inspire Record 212895 DOI 10.17182/hepdata.20368

We have measured the differential cross section for p¯p and pp elastic scattering at s=53 GeV in the interval 0.5<|t|<4.0 (GeV/c)2 at the CERN intersecting storage rings using the split-field magnet detector. The shape of the differential cross section differs significantly between p¯p and pp scattering in the region 1.1<|t|<1.5 (GeV/c)2, with p¯p data showing a less pronounced dip structure than pp data.

MEASUREMENTS OF SPIN CORRELATION PARAMETER A(NN) AND ANALYZING POWER AT 90-degrees FOR P (polarized) P (polarized) ---> D PI+ BETWEEN 500-MEV AND 800-MEV

Measurements of the spin observables ANN(90∘) and AN0(90∘) for the reaction pp→dπ+ between 500 and 800 MeV are presented and compared with previous measurements and with predictions from theories and a partial-wave analysis. These are the first available measurements of ANN above 590 MeV.

Charged Multiplicity of Hadronic Events Containing Heavy Quark Jets

Rowson, P.C. ; Trilling, G. ; Abrams, G.S. ; et al.
Phys.Rev.Lett. 54 (1985) 2580-2583, 1985.
Inspire Record 212819 DOI 10.17182/hepdata.20380

The charged-particle multiplicities of hadronic events deriving from produced bottom or charm quarks have been measured in the Mark II detector at PEP in e+e− annihilation at 29GeV. For events containing one semileptonic and one hadronic weak decay, we find multiplicities of 15.2±0.5±0.7 for bottom and 13.0±0.5±0.8 for charm. The corresponding multiplicities of charged particles accompanying the pair of heavy hadrons are 5.2±0.5±0.9 for bottom, and 8.1±0.5±0.9 for charm.
