Anti-p-p backward elastic scattering from 0.7 to 2.16 gev/c

Yoh, J.K. ; Barish, B.C. ; Nicholson, H. ; et al.
Phys.Rev.Lett. 23 (1969) 506-510, 1969.

Elastic scattering of p¯ on p has been studied for cosθc.m. between -0.88 and -1.0 and Plab(p¯) between 0.70 and 2.16 GeV/c. The momentum dependence of the cross section shows a sharp dip at 0.9 GeV/c and a broad peaking around 1.4 GeV/c. The possibility of the peak resulting from direct formation of boson resonances has been studied. Alternatively, a diffraction model agrees qualitatively with our data and other elastic data at different angles.

Anti-p p annihilation into pi+ rho at small angles between 1 and 2 gev/c

Inspire Record 69017 DOI 10.17182/hepdata.21588

We have studied the process p¯p into π+X− using wire spark chambers. The data cover the angular range of cosθp¯π+* between 0.96 and 1.0 at several incident momenta between 1 and 2 GeVc. The reaction p¯p→π+ρ− was observed with (dσdΩ)* of the order of 100 μb/sr at several momenta.

Precise Determination of Sin**2-$\theta^-$w From Measurements of the Differential Cross-sections for $\nu_\mu p \to \nu_\mu p$ and $\bar{\nu}_\mu p \to \bar{\nu}_\mu p$

Inspire Record 218044 DOI 10.17182/hepdata.20261

This paper describes measurements of the semileptonic weak-neutral-current reactions νpμ→νpμ and ν¯pμ→ν¯pμ which yield the absolute differential cross sections dσ(νpμ)dQ2 and dσ(ν¯pμ)dQ2. The weak-neutral-current parameter, sin2θW, is determined to be sin2θW=0.220±0.016(stat.)(syst.)−0.031+0.023.

Search for Narrow States by Detection of Monochromatic $\gamma$ Rays in $\bar{p} p$ Annihilation at Rest

The Fukui-Tokyo-KEK-Kyoto Sangyo-Osaka-Tokyo Metropolitan collaboration Chiba, M. ; Doi, K. ; Fujitani, T. ; et al.
Phys.Lett.B 177 (1986) 217-222, 1986.
Inspire Record 229794 DOI 10.17182/hepdata.30244

An inclusive γ ray spectrum in p̄p annihilation at rest has been measured with modularized NaI(Tℓ) detectors with statistics several times higher than before. The aim of the experiment was to search for baryonium B in p̄p → γB by detection of narrow lines in the γ ray spectrum. We have not observed any narrow state B with yield greater than 1.5 × 10 −3 per annihilation and with statistical significance higher than 2σ.

Measurement of Neutrino - Proton and anti-neutrino - Proton Elastic Scattering

Ahrens, L.A. ; Aronson, S.H. ; Connolly, P.L. ; et al.
Phys.Rev.D 35 (1987) 785, 1987.
Inspire Record 18763 DOI 10.17182/hepdata.23350

Measurements of the semileptonic weak-neutral-current reactions νμp→νμp and ν¯μp→ν¯μp are presented. The experiment was performed using a 170-metric-ton high-resolution target detector in the BNL wide-band neutrino beam. High-statistics samples yield the absolute differential cross sections dσ(νμp)/dQ2 and dσ(ν¯μp)/dQ2. A measurement of the axial-vector form factor GA(Q2) is also presented. The results are in good agreement with the standard model SU(2)×U(1). The weak-neutral-current parameter sin2thetaW is determined to be sin2θW=0.220±0.016(stat)−0.031+0.023(syst).

Measurement of the Weak Neutral Current Coupling Constants of the Electron and Limits on the Electromagnetic Properties of the Muon Neutrino

Abe, K. ; Ahrens, L.A. ; Amako, K. ; et al.
Phys.Rev.Lett. 58 (1987) 636-639, 1987.
Inspire Record 246621 DOI 10.17182/hepdata.20185

The weak coupling constants of the electron, gVe and gAe, are determined from measurements of the total and differential cross sections for the reaction νμe→νμe. The data also place limits of interest on the magnitudes of a neutrino charge radius and a possible neutrino magnetic dipole moment.

rivet Analysis
Measurement of R and Search for New Heavy Quarks in $e^+ e^-$ Annihilation at 50-{GeV} and 52-{GeV} Center-of-mass Energies

The Venus collaboration Yoshida, H. ; Chiba, Y. ; Endo, I. ; et al.
Phys.Lett.B 198 (1987) 570, 1987.
Inspire Record 251274 DOI 10.17182/hepdata.30074

The total cross section for the process of the e + e - annihilation into hadrons has been measured at the centre-of-mass energies of 50 GeV and 52 GeV and a search has been made for new heavy quarks. The ratios R = σ ( e + e - → hadrons )/ σ point ( e + e - → μ + μ - ) obtained are 4.4±0.5 at 50 GeV and 4.7±0.3 at 52 GeV, respectively. An additional systematic uncertainty is 10%. From the event shape analysis we found no evidence for a new quark with charge 2 3 e .
