n p elastic spin transfer measurements at 485-MeV and 635-MeV

McNaughton, K.H. ; Ambrose, D.A. ; Coffey, P. ; et al.
Phys.Rev.C 46 (1992) 47-51, 1992.
Inspire Record 342389 DOI 10.17182/hepdata.26097

We have measured the spin-transfer parameters KLL, KSL, KLS, and KSS at 635 MeV from 50° to 178° c.m. and at 485 MeV from 74° to 176° c.m. These new data have a significant impact on the phase-shift analyses. There are now sufficient data near these energies to overdetermine the elastic nucleon-nucleon amplitudes.

n p elastic analyzing power A(NO) and spin transfer K(NN)

McNaughton, M.W. ; Johnston, K. ; Swenson, D. ; et al.
Phys.Rev.C 48 (1993) 256-265, 1993.
Inspire Record 34401 DOI 10.17182/hepdata.51045

We have measured the analyzing power ANO and the spin transfer KNN for np-elastic scattering from about 60° to 170° c.m. at 485, 635, and 788 MeV. The new data clarify previous discrepancies and complete the first-order determination of nucleon-nucleon elastic scattering at these energies.

eta' photoproduction on the proton for photon energies from 1.527-GeV to 2.227-GeV.

The CLAS collaboration Dugger, M. ; Ball, J.P. ; Collins, P. ; et al.
Phys.Rev.Lett. 96 (2006) 062001, 2006.
Inspire Record 700399 DOI 10.17182/hepdata.31553

Differential cross sections for the reaction gamma p -> eta-prime p have been measured with the CLAS spectrometer and a tagged photon beam with energies from 1.527 to 2.227 GeV. The results reported here possess much greater accuracy than previous measurements. Analyses of these data indicate for the first time the coupling of the etaprime N channel to both the S_11(1535) and P_11(1710) resonances, known to couple strongly to the eta N channel in photoproduction on the proton, and the importance of j=3/2 resonances in the process.

Z gamma production in anti-p p collisions S**(1/2) = 1.8-TeV and limits on anomalous Z Z gamma and Z gamma gamma couplings

The D0 collaboration Abbott, B. ; Abolins, M. ; Acharya, Bannanje Sripath ; et al.
Phys.Rev.D 57 (1998) R3817-R3821, 1998.
Inspire Record 465977 DOI 10.17182/hepdata.42169

We present a study of Z +gamma + X production in p-bar p collisions at sqrt{S}=1.8 TeV from 97 (87) pb^{-1} of data collected in the eegamma (mumugamma) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent with the Standard Model predictions. We obtain limits on anomalous ZZgamma and Zgammagamma couplings for form factor scales Lambda = 500 GeV and Lambda = 750 GeV. Combining this analysis with our previous results yields 95% CL limits |h{Z}_{30}| < 0.36, |h{Z}_{40}| < 0.05, |h{gamma}_{30}| < 0.37, and |h{gamma}_{40}| < 0.05 for a form factor scale Lambda=750 GeV.

CONST(NAME=SCALE) is the model parameter, used in the modification of the couplings as follows: h = hi0/(1 + M(gamma Z)**2/CONT(NAME=SCALE)**2)**n. See article for details.


Wide Angle Differential Cross-Sections for Elastic Proton Proton Scattering in the Region of Delta (1236) Production

Abe, K. ; Barnett, B.A. ; Goldman, J.H. ; et al.
Phys.Rev.D 12 (1975) 1-5, 1975.
Inspire Record 103521 DOI 10.17182/hepdata.24866

Differential cross sections for p−p elastic scattering are presented with scattering angles in the center-of-mass system greater than 35° to 50°. The data were obtained at incident laboratory momenta 0.857, 1.091, 1.210, 1.374, 1.405, and 1.501 GeV/c. This spans the region of the onset of Δ(1236) production and where a possible spin-singlet D-wave resonance is indicated in an analysis of earlier data.

W**2 and Q**2 dependence of charged hadron and pion multiplicities in neutrino p and anti-neutrino p charged current interactions

The WA21 collaboration Jones, G.T. ; Jones, R.W.L. ; Morrison, Douglas R.O. ; et al.
Z.Phys.C 46 (1990) 25-34, 1990.
Inspire Record 305244 DOI 10.17182/hepdata.1699

Using data onvp and\(\bar vp\) charged current interactions from a bubble chamber experiment with BEBC at CERN, the average multiplicities of charged hadrons and pions are determined as functions ofW2 andQ2. The analysis is based on ∼20000 events with incidentv and ∼10000 events with incident\(\bar v\). In addition to the known dependence of the average multiplicity onW2 a weak dependence onQ2 for fixed intervals ofW is observed. ForW>2 GeV andQ2>0.1 GeV2 the average multiplicity of charged hadrons is well described by〈n〉=a1+a2ln(W2/GeV2)+a3ln(Q2/GeV2) witha1=0.465±0.053,a2=1.211±0.021,a3=0.103±0.014 for thevp anda1=−0.372±0.073,a2=1.245±0.028,a3=0.093±0.015 for the\(\bar vp\) reaction.
