## Plots from Rivet analyses## Jet rates and event shapes at LEP I and II (ALEPH_2004_S5765862)Spires | 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. ## $\eta$ and $\omega$ Production in Hadronic $Z^0$ Decays (ALEPH_2002_S4823664)Spires | Phys.Lett. B528 (2002) 19-33 | hep-ex/0201012 The production of $\eta$ and $\omega$ mesons measured using 4 millon $Z^0$ events by the ALEPH experiment at LEP. Only the fragmentation functions are implemented. ## Study of the fragmentation of b quarks into B mesons at the Z peak (ALEPH_2001_S4656318)Spires | 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)Spires | 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)Spires | 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. ## Measurement of the quark to photon fragmentation function (ALEPH_1996_S3196992)Spires | Z.Phys.C69:365-378,1996 | doi:10.1007/s002880050037 Earlier measurements at LEP of isolated hard photons in hadronic Z decays, attributed to radiation from primary quark pairs, have been extended in the ALEPH experiment to include hard photon production inside hadron jets. Events are selected where all particles combine democratically to form hadron jets, one of which contains a photon with a fractional energy $z > 0.7$. After statistical subtraction of non-prompt photons, the quark-to-photon fragmentation function, $D(z)$, is extracted directly from the measured 2-jet rate. ## Hadronic Z decay charged multiplicity measurement (ALEPH_1991_S2435284)Spires | 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. ## Study of the b-quark fragmentation function at LEP 1 (DELPHI_2002_069_CONF_603)DELPHI note 2002-069-CONF-603 (ICHEP 2002) Measurement of the $b$-quark fragmentation function by DELPHI using 1994 LEP 1 data. The fragmentation function for both weakly decaying and primary $b$-quarks has been determined in a model independent way. Nevertheless the authors trust $f(x_B^\text{weak})$ more than $f(x_B^\text{prim})$. ## Hadronization properties of $b$ quarks compared to light quarks in $e^+ e^-\to q \bar{q}$ from 183\;GeV to 200\;GeV (DELPHI_2000_S4328825)Spires | Phys.Lett.B479:118-128,2000 | hep-ex/0103022 | DELPHI 2002-052 CONF 586 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 energies above the $Z^0$ mass.

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. ## Strange baryon production in $Z$ hadronic decays at Delphi (DELPHI_1995_S3137023)Spires | Z.

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)Spires | Phys.
