    A measurement of the form factor ratios in the decay D+ → K*(892)0μ+ν is obtained by fitting to the decay angles and q2 of 305 events. The results, evaluated at q2 = 0, are A2(0)/A1(0) = 0.82+0.22 -0.23 (stat.)±0.11 (sys.) and V(0)/A1(0) = 2.00+0.34 -0.32±0.16, where A1 and A2 are the axial vector form factors and V is the vector form factor. The corresponding ratio of the longitudinal to transverse polarization of the K*0 is 1.18±0.18±0.08. These results are compared with other experimental results and with theoretical predictions. © 1992.

    We present results on charm pair correlations measured in proton-emulsion interactions at s=38.7 GeV. The predictions of leading order QCD for the distributions in invariant mass, rapidity gap, xF, and polar angle in the charm pair CMS are qualitatively consistent with our measurements. The mean pT of the pairs is equal within errors to that measured in dilepton production at the same energy and mass range. © 1991.

    We report results on D0 and D+ production in proton-emulsion interactions at s=38.7 GeV. A fit to the form (1-|xF|)n exp (-bp 2 T) yields n=6.9 +1.9 -1.8 and b=0.84 +0.10 -0.08(GeV/c)-2. The total inclusive cross section, is assuming linear A dependence, is measured to be 38±3(stat.) ±13 (sys.) μb for the D0 and 38±9±14 μb for the D+. A comparison of these results with previous measurements indicates that nuclear effects do not strongly influence charm production. The predictions of QCD are in good agreement with our data. © 1991.

    We have studied 80 events of candidates for XI-capture star at rest in nuclear emulsion, where XI- hyperons are produced in (K-, K+) reactions identified by a K+ spectrometer. The weak decay of heavy double hypernuclei is confirmed, studying the distribution of visible energy-release and the probability of emission of two fast protons, in comparison with those for single hypernuclei.

    The fraction f of D0 semimuonic decays which occur through the K mode has been measured in a hybrid emulsion spectrometer. Analysis of 124 semimuonic D0-decay candidates gives f=0.320.05 (stat) 0.05 (syst). From this measurement and existing data on the D0 semileptonic branching ratio and lifetime, we obtain the branching ratio R(D0K-)=(2.40.40.5)% and partial decay rate (D0K-)=(5.60.91.2)×1010 s-1. © 1991 The American Physical Society.

    An ultra-high speed (approximately 80000 rpm) version of a previously announced compact parametric motor was described. A specially developed gaseous bearing was employed, and the exciter magnetic circuit was toroidally wound 0.1 mm thick Fe-Si sheet. Application of an AC sinusoidal voltage at frequencies 1.3 kHz and 1.0 kHz resulted in the anticipated speeds, about 80000 and 60000 rpm, respectively. © 1986 IEEE
