A Study of the Omega-Zero Spin-Density Matrix Elements in the Reaction Pi-Minus Proton Goes to Omega-Zero Neutron at 3.65, 4.5, and 5.5 GeV/c
… to detect events of the type + TI p-TI TI yyn. Incident pions of momenta 3.65, 4.5, and 5.5 GeV/c were produced by an internal target at the Argonne National Laboratory Zero Gradient Synchrotron. The values obtained for the WO spin-density matrix elements are inconsistent with the predictions of …

Comparison of pion- and proton- production of charmonium
… from X decay is measured to be 0.33±O.07 for incident pions and 0.47±0.2l for incident protons. The X(35l0) and X(3555) are produced in roughly equal numbers for pions, but the X(3555) dominates for protons. Simple gluon fusion accounts for X production by protons. This is reasonable …

Comparison of Pion- and Proton-Production of Charmonium
… decay is measured to be 0.33 (+OR-) 0.07 for incident pions and 0.47 (+OR-) 0.21 for incident protons. The (chi)(3510) and (chi)(3555) are produced in roughly equal numbers for pions, but the (chi)(3555) dominates for protons. Simple gluon fusion accounts for (chi) production by protons. This …

A-2 meson production in pi-minus proton interactions at five BeV
… cross. section measurements reported at other incident pion momenta. The spin-parity analysis of the Ppi decay mode yields results p + which are consistent with a J = 2 assignment for both halves of the A2"" The angular distribution of the decay plane indicates a J = 2 spin state with alkl = 1 …
