Precise measurements of the differential cross sections on the π − p→ π 0 n charge exchange scattering have been performed at six incident beam momenta of 1969, 2172, 2370, 2569, 2767 and 2965 MeV/ c covering a wide angular range of −0.95 < cos θ π ∗ < 0.95, where θ π ∗ is an emission angle of π 0 meson in the c.m.s. The results are compared with predictions of recent partial wave analyses.

A Measurement of the Proton Structure Functions From Neutrino Hydrogen and Anti-neutrino Hydrogen Charged Current Interactions

The Birmingham-CERN-Imperial Coll.-MPI(Munich)-Oxford-University Coll. collaboration Jones, G.T. ; Jones, R.W.L. ; Kennedy, B.W. ; et al.

Within the framework of the quark-parton model, the quark and anti-quark structure functions of the proton have been measured by fitting them to the distributions of the events in the Bjorkeny variable. The data used form the largest sample of neutrino and antineutrino interactions on a pure hydrogen target available, and come from exposures of BEBC to the CERN wide band neutrino and antineutrino beams. It is found that the ratiodv/uv of valence quark distributions falls with increasing Bjorkenx. In the context of the quark-parton model the results constrain the isospin composition of the accompanying diquark system. Models involving scattering from diquarks are in disagreement with the data.

New Results From Asp on Single Photon Production at $\sqrt{s}$ 29-{GeV}

Hearty, C. ; Rothberg, J.E. ; Young, K.K. ; et al.

Inspire Record 244697 DOI 10.17182/hepdata.20171

This Letter reports results of a search for radiative production, by e+e− annihilation of particles that interact only weakly in matter. The search has been made in the total data set of 115 pb−1 acquired with the ASP detector at the SLAC storage ring PEP (s=29 GeV). No anomalous signal was observed. The number of generations of light neutrinos has been limited to Nν<7.5 (90% confidence level). Limits are also placed on the masses of particles predicted to exist by models of supersymmetry.

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.

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
Observation of $e^+ e^- \to D(s$)+- $D^*(s$)-+ at $\sqrt{s}=4$.14-{GeV}

The MARK-III collaboration Blaylock, G. ; Bolton, T. ; Brown, J.S. ; et al.

Inspire Record 244856 DOI 10.17182/hepdata.20170

We present evidence for the exclusive reaction e+e−→Ds±Ds*∓, observed with the Mark III detector at the SLAC storage ring SPEAR. The Ds± is reconstructed in the φπ± decay mode, while the Ds*∓ is detected as a narrow peak in the recoil-mass distribution. The mass of the Ds* is found to be 2109.3±2.1±3.1 MeV/c2, yielding a Ds*−Ds mass difference of 137.9±2.1±4.3 MeV/c2. The width of the Ds* is <22 MeV/c2 at the 90%-confidence level. The observed signal corresponds to σ(e+e−→Ds+Ds*−+Ds−Ds*+)B(Ds+→φπ+)=30±6±11 pb at s=4.14 GeV.
