Inspire Record 177606 DOI 10.17182/hepdata.20572

The production of the charmed meson state D*+ has been observed in e+e− annihilation at 29 GeV. The fragmentation function for charmed quarks appears to be peaked about z=0.5.

Inspire Record 171070 DOI 10.17182/hepdata.20563

Energy correlations have been measured with the MARK II detector at the PEP storage ring (Stanford Linear Accelerator Center) at c.m. energy of 29 GeV and are compared to first-order QCD predictions. Fragmentation processes are significant and limit the precision with which the first-order strong-coupling constant can be determined.

POLARIZATION AND ANGULAR DISTRIBUTIONS IN ELASTIC P P SCATTERING AT 100-GEV AND 300-GEV.

Phys.Rev.Lett. 41 (1978) 781-784, 1978.
Inspire Record 132550 DOI 10.17182/hepdata.20889

Measurements of the polarization parameter and angular distributions in pp elastic scattering at incident energies of 100 and 300 GeV are reported. The data cover the kinematic range 0.18<−t<2.0 GeV2. They are found to be consistent with absorption-model predictions.
