Polarization of Muoproduced J/psi (3100)

Clark, A.R. ; Johnson, K.J. ; Kerth, L.T. ; et al.
Phys.Rev.Lett. 45 (1980) 2092, 1980.
Inspire Record 155741 DOI 10.17182/hepdata.20697

The polarization and Q2 dependence of muoproduced ψ→μ+μ− have been analyzed in a magnetized-steel calorimeter at Fermilab. The reaction γVN→ψN is found to be helicity conserving. Even after allowance for possible Q2 dependence of the decay angular distribution, the ψ muoproduction cross section falls more steeply in Q2 than predicted by ψ dominance.

We observe a K−π+ state at 1786 ± 8 MeV with a width 95 ± 31 MeV in the reaction K−p→K−π+n at 6 GeV/c, from an experiment carried out at the Brookhaven National Laboratory multiparticle spectrometer.

Reaction K- p --> Lambda pi0 from 1647-MeV to 1715-MeV

Ponte, R.A. ; Hertzbach, Stanley S. ; Button-Shafer, Janice ; et al.
Phys.Rev.D 12 (1975) 2597-2609, 1975.
Inspire Record 104824 DOI 10.17182/hepdata.24846

This paper contains the results of a study of the reaction K−p→Λπ0 in the center-of-mass-system-energy region of 1647 to 1715 MeV. An energy-dependent partial-wave analysis was performed in this channel. Two allowable solutions were obtained. The first solution in this region contains the D13[t=0.08±0.01, Γ(ER)=44±11 MeV, and ER=1671±3 MeV] partial wave as the only resonant amplitude; the second solution contains both the P11[t=0.16±0.01, Γ(ER)=81±10 MeV, and ER=1671±2 MeV] and the D13[t=0.17±0.01, Γ(ER)=76±5 MeV, and ER=1655±2 MeV] partial wave as resonant.
