Inspire | HepData | Analysis reference | Eur.Phys.J.C35:457-486,2004 | doi:10.1140/epjc/s2004-01891-4 | http://cdsweb.cern.ch/record/690637/files/ep-2003-084.pdf

Jet rates, event-shape variables and inclusive charged particle spectra are measured in $e^+ e^-$ collisions at CMS energies between 91 and 209 GeV. The previously published data at 91.2 GeV and 133 GeV have been re-processed and the higher energy data are presented here for the first time. Note that the data have been corrected to include neutrinos. Beam energy must be specified as analysis option "ENERGY" when rivet-merging samples.

Study of the fragmentation of b quarks into B mesons at the Z peak (ALEPH_2001_S4656318)

Inspire | HepData | Analysis reference | Phys.Lett.B512:30-48,2001. | hep-ex/0106051

Measurement of the $b$-quark fragmentation function by ALEPH using LEP 1 data. The fragmentation function for both weakly decaying and leading $b$-quarks has been determined. The data used for the plots has been renormalised to give a differential distribution rather than the bin-by-bin average in HEPDATA.

Scaled energy distribution of $D^*$ at LEP (ALEPH_1999_S4193598)

Inspire | HepData | Analysis reference | Eur.Phys.J.C16:597-611,2000 | hep-ex/9909032 | CERN-EP-99-094

Study of charm production in $Z$ decays. Here, only the scaled energy distribution of $D^{*\pm}$ is implemented. Should be very important for fragmentation tuning.

Studies of QCD with the ALEPH detector. (ALEPH_1996_S3486095)

Inspire | HepData | Analysis reference | Phys. Rept., 294, 1--165 (1998)

Summary paper of QCD results as measured by ALEPH at LEP 1. The publication includes various event shape variables, multiplicities (identified particles and inclusive), and particle spectra.

Hadronic Z decay charged multiplicity measurement (ALEPH_1991_S2435284)

Inspire | HepData | Analysis reference | Phys. Lett. B, 273, 181 (1991)

The charged particle multiplicity distribution of hadronic Z decays, as measured on the peak of the Z resonance using the ALEPH detector at LEP. The unfolding procedure was model independent, and the distribution was found to have a mean of $20.85 \pm 0.24$, Comparison with lower energy data supports the KNO scaling hypothesis. The shape of the multiplicity distribution is well described by a log-normal distribution, as predicted from a cascading model for multi-particle production.

Delphi MC tuning on event shapes and identified particles. (DELPHI_1996_S3430090)

Inspire | HepData | Analysis reference | Z.Phys.C73:11-60,1996 | doi:10.1007/s002880050295

Event shape and charged particle inclusive distributions measured using 750000 decays of Z bosons to hadrons from the DELPHI detector at LEP. This data, combined with identified particle distributions from all LEP experiments, was used for tuning of shower-hadronisation event generators by the original PROFESSOR method. This is a critical analysis for MC event generator tuning of final state radiation and both flavour and kinematic aspects of hadronisation models.

Measurement of the b-quark fragmentation function in $Z^0$ decays (SLD_2002_S4869273)

Inspire | HepData | Analysis reference | Phys. Rev.D65:092006,2002 | hep-ex/0202031

Measurement of the $b$-quark fragmentation function by SLC. The fragmentation function for weakly decaying $b$-quarks has been measured.

Charged particle multiplicities in heavy and light quark initiated events on the $Z^0$ peak (SLD_1996_S3398250)

Inspire | HepData | Analysis reference | Phys.Lett.B386:475-485,1996 | hep-ex/9608008

Measurements of the mean charged multiplicities separately for $b\bar b$, $c\bar c$ and light quark ($uds$) initiated events in $e^+e^-$ interactions at the $Z^0$ mass.

Jet rates in $e^+e^-$ at JADE [35--44 GeV] and OPAL [91--189 GeV]. (JADE_OPAL_2000_S4300807)

Inspire | HepData | Analysis reference | Eur.Phys.J.C17:19-51,2000 | arXiv:hep-ex/0001055

Differential and integrated jet rates for Durham and JADE jet algorithms. The integration cut value used for the integrated rate observables is not well-defined in the paper: the midpoint of the differential bin has been used thanks to information from Stefan Kluth and Christoph Pahl. We anyway recommend that the differential plots be preferred over the integrated ones for MC generator validation and tuning, to minimise correlations.

Hadron multiplicities in hadronic $e^+e^-$ events (PDG_HADRON_MULTIPLICITIES)

Inspire | HepData | Analysis reference | Phys. Lett. B, 667, 1 (2008)

Hadron multiplicities in hadronic $e^+e^-$ events, taken from Review of Particle Properties 2008, table 40.1, page 355. Average hadron multiplicities per hadronic $e^+e^-$ annihilation event at $\sqrt{s} \approx {}$ 10, 29--35, 91, and 130--200 GeV. The numbers are averages from various experiments. Correlations of the systematic uncertainties were considered for the calculation of the averages. Beam energy must be specified as analysis option "ENERGY" when rivet-merging samples.
