A high precision measurement of the υ-meson mass has been performed at the storage ring VEPP-4 using the MD-1 detector. The resonance depolarization method has been used for the absolute calibration of the beam energy that allowed to improve the accuracy of υ-mass measurement by a factor of ten. The following mass value has been obtained: M = 9459.7 ± 0.6 MeV.

Inclusive $K^*$+ (890), $K^*$+ (1430) and $\bar{K}^*$ (890) Production in $K^+ p$ Interactions at 32-{GeV}/$c$

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Borovikov, A.A. ; et al.
Z.Phys.C 25 (1984) 103, 1984.
Inspire Record 195755 DOI 10.17182/hepdata.47703

We present final results on inclusive production ofK*+(890),K*+(1430) andK*−(890) in\(\bar K^ +p\) interactions at 32 GeV/c, based on a statistics of ∼27 events/μb. Total cross sections,pT-andx-dependence of inclusive distributions are compared with experiments at other energies and with the Lund fragmentation model. Spin density matrix elements of theK*+(890) are also discussed. The results suggest that “recombination” of both initial state valence quarks\(\bar s\) andu of theK+ intoK*+(890), responsible in the Lund model for ∼45% of theK*+(890) cross section, is strongly suppressed.

$D$ Meson Branching Ratios and Hadronic Charm Production Cross-sections

The LEBC-EHS collaboration Aguilar-Benitez, M. ; Allison, W.W.M. ; Bagnaia, P. ; et al.
Phys.Lett.B 135 (1984) 237-242, 1984.
Inspire Record 193696 DOI 10.17182/hepdata.30599

A determination of branching ratios for D meson decays into all charged particle final states is reported. The values obtained: (D ± → K ∓ π ± π ± /all D ± ) = (14 ± 6)% and ( D 0 /D 0 → K ± π ∓ π + π − /all D 0 /D 0 ) = (10 ± 4)%, are higher than those currently accepted. This result, if confirmed, implies a corresponding reduction in the accepted values for some total cross section measurements. Revised inclusive cross sections for D meson production in the forward hemisphere in π − p and pp interactions at 360 GeV/ c , are presented.

Investigation of inclusive reactions with production of meson resonances in pion-carbon interactions at 5 GeV/c

Inspire Record 201950 DOI 10.17182/hepdata.69761

Total inclusive cross sections for rho0, ω and f (1270) meson production and the corresponding average multiplicities < n(rho0) > = 0.072+-0.019, < n(ω) > = 0.033+-0.022, < n(f) > = 0 01 +-0.010 have been measured in π-C interactions at 5 GeV/c. It is shown that approximately 8 percent of secondary π- mesons are produced from the meson resonance decay. For the reactions with the production of rho0 mesons the dependence of the inclusive differential cross sections on the rapidity and squared transverse momentum is analysed
