A Measurement of High $P_T$ Correlations in 340-GeV/c pp and 280-GeV/c $\pi^- p$ Reactions

Oliver, W.P. ; Limon, P. ; Mantsch, Paul M. ; et al.
Nucl.Phys.B 228 (1983) 439-463, 1983.
Inspire Record 189533 DOI 10.17182/hepdata.33923

We have measured correlations between single high- p T (1.5< p T <3.5 GeV/ c ) trigger particles on one side of the beam line and groups of particles entering a calorimeter on the opposite side of the beam line. The mean transverse momentum measured in the calorimeter is found to increase with the trigger-particle transverse momentum. The coplanarity of the events increases with trigger-particle transverse momentum. We have compared our data with the predictions of a phenomenological four-jet model. To fit our data we find that we must give large (0.9 GeV/ c ) mean transverse momenta to the constituents of the initial hadrons.

A Measurement of the Branching Fraction of the Decay $\Upsilon$ (1s) $\to \tau^+ \tau^-$

The CLEO collaboration Giles, R. ; Hassard, J. ; Hempstead, M. ; et al.

The branching fraction for the decay of the ϒ(1S) into τ paris has been measured to be (3.4±0.4±0.4)%. This result agrees with the previously measured branching ratio of the decay into muon pairs.

Measurement of Elastic electron - Neutron Cross-Sections Up to Q**2 = 10-(GeV/c)**2

Rock, Stephen ; Arnold, R.G. ; Bosted, Peter E. ; et al.
Phys.Rev.Lett. 49 (1982) 1139, 1982.
Inspire Record 179135 DOI 10.17182/hepdata.20575

The elastic electron-neutron cross section has been measured at four-momentum transfers squared (Q2) of 2.5, 4.0, 6.0, 8.0, and 10.0 (GeV/c)2 with use of a deuterium target and detection of the scattered electrons at 10°. The ratio of neutron to proton elastic cross sections decreases with Q2. At high Q2 this trend is inconsistent with the dipole law, form-factor scaling, and many vector dominance models, although it is consistent with some parton models.

Inclusive Charged $D^*$ Production in $e^+ e^-$ Annihilations at $W=10$.4-{GeV}

The CLEO collaboration Bebek, C. ; Hassard, J. ; Hempstead, M. ; et al.
Phys.Rev.Lett. 49 (1982) 610, 1982.
Inspire Record 178490 DOI 10.17182/hepdata.20565

A measurement is presented of inclusive charged D*(2010) production from nonresonant e+e− annihilation in the center-of-mass energy (W) range 10.2 GeV<W<10.6 GeV. Charged D* mesons are identified by the decays D*+→D0π+→K−π+π+ and the charge conjugate mode. It is found that 40 ± 7 ± 13% of the charm quarks from the process e+e−→cc¯ result in D* mesons with z>0.7 (z=2EW, where E is the D* energy).

Charged Particle Multiplicities in $B$ Meson Decay

The CLEO collaboration Alam, M.S. ; Csorna, S.E. ; Fridman, A. ; et al.
Phys.Rev.Lett. 49 (1982) 357, 1982.
Inspire Record 178492 DOI 10.17182/hepdata.20573

The charged multiplicity has been measured at the ϒ(4S) and a value of 5.75±0.1±0.2 has been obtained for the mean charged multiplicity in B-meson decay. Combining this result with the measurement of prompt leptons from B decay, the values 4.1±0.35±0.2 and 6.3±0.2±0.2 are found for the semileptonic and nonleptonic charged multiplicities, respectively. If b→c dominance is assumed for the weak decay of the B meson, then the semileptonic multiplicity is consistent with the recoil mass determined from the lepton momentum spectrum.
