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.

Measurement of $\pi^0$, $\eta$, $\eta^\prime$, $K^0_S$ and $\Lambda^0$ spectra in two and three jet events. In addition to the normal inclusive spectra the spectra in individual jets are measured for three jet events.

Studies of QCD with the ALEPH detector. (ALEPH_1996_S3486095)

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

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.

Rapidity structure of $p\bar{p}$ pairs (DELPHI_2000_I531568)

Inspire | HepData | Analysis reference | Phys.Lett.B 490 (2000) 61-70

Rapidity-rank structure of $p\bar{p}$ pairs, the relative occurrence of the rapidity-ordered configuration $pM\bar{p}$, where $M$ is a meson, and that of adjacent $p\bar{p}$ pairs is compared as a function of the rapidity w.r.t the thrust axis.

Events shapes at MZ as function of thrust direction (DELPHI_2000_I522656)

Inspire | HepData | Analysis reference | Eur.Phys.J.C 14 (2000) 557-584, 2000

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.

Correlations between $\Lambda^0$ and $\bar{\Lambda}^0$ production in hadronic $Z^0$ decays (DELPHI_1993_I360638)

Inspire | HepData | Analysis reference | Phys.Lett. B318 (1993) 249-262, 1993

The spectrum for the production of $\Lambda^0$ and $\bar{\Lambda}^0$ in hadronic $Z^0$ decays. Importantly the rapidity difference and cosine of the angle between $\Lambda^0$ and $\bar{\Lambda}^0$ baryons is measured. This is sensitive to different models of baryon production.

Quark and gluon jet fragmentation functions (OPAL_2004_I648738)

Inspire | HepData | Analysis reference | Eur.Phys.J. C37 (2004) no.1, 25-47 | hep-ex/0404026

Measurement of the fragmentation functions for quarks and gluons at LEP. Useful for studying the properties of gluon jets and the differences between quark and gluon jets. For the study of gluon jets the fictional $e^+e^-\to g g $ process must be used. The data in histograms labelled "hemisphere fragmentation" are measured from jets defined by hemispheres, with an energy scale defined by $E=\sqrt{s}/2$, while data in histograms named "durham fragmentation" are measured from jets defined by the durham algorithm with $Q_\mathrm{jet}=E_\mathrm{jet}\sin(\theta/2)$ as the energy scale. The rivet analysis defines the jet flavour from the initial quarks, as the data are corrected for impurities, and defines all jets as hemispheres with energy scale $E=\sqrt{s}/2$.

Inspire | HepData | Analysis reference | Eur.Phys.J.C29:463-478,2003 | doi:10.1140/epjc/s2003-01229-x | arXiv:hep-ex/0210031

A study of b quark fragmentation function is presented using inclusively reconstructed weakly decaying B hadrons. The measurement uses about four million hadronic Z decays recorded in 1992-2000 with the OPAL detector at LEP.

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.
