Description:
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.
Run details:
e+ e- -> jets with $\pi$ and $\eta$ decays turned off.

Description:
Measurement of transverse momentum and total cross section of $e^+e^-$
pairs in the Z-boson region of $66~\text{GeV}/c^2 < m_{ee} <
116~\text{GeV}/c^2$ from pbar-p collisions at sqrt(s) = 1.8 TeV, with the
Tevatron CDF detector. The Z pT, in a fully-factorised picture, is
generated by the momentum balance against initial state radiation (ISR)
and the primordial/intrinsic pT of the Z's parent partons in the incoming
hadrons. The Z pT is important in generator tuning to fix the interplay
of ISR and multi-parton interactions (MPI) ingenerating `underlying
event' activity. This analysis is subject to ambiguities in the
experimental Z pT definition, since the Rivet implementation reconstructs
the Z momentum from the dileptonpair with finite cones for photon brem
summation, rather than YFS/shower unfolding or non-portable direct use of
the Z in the event record.
Run details:
ppbar collisions at 1800 GeV. $Z/\gamma*$ Drell-Yan events with $e^+e^-$
decay mode only.

Description:
The original CDF underlying event analysis, based on decomposing each
event into a transverse structure with ``toward'', ``away'' and
``transverse'' regions defined relative to the azimuthal direction of the
leading jet in the event. Since the toward region is by definition
dominated by the hard process, as is the away region by momentum balance
in the matrix element, the transverse region is most sensitive to multi-
parton interactions. The transverse regions occupy $|\phi| \in
[60\degree, 120\degree]$ for $|\eta| < 1$. The pT ranges for the leading
jet are divided experimentally into the `min-bias' sample from 0--20 GeV,
and the `JET20' sample from 18--49 GeV.
Run details:
ppbar QCD interactions at 1800 GeV. The leading jet is binned from 0--49
GeV, and histos can usually can be filled with a single generator run
without kinematic sub-samples.

Description:
A study of ppbar collisions at sqrt(s) = 1800 and 630 GeV collected using
a minimum bias trigger in which the data set is divided into two classes
corresponding to `soft' and `hard' interactions. For each subsample, the
analysis includes measurements of the multiplicity, transverse momentum
(pT) spectra, and the average pT and event-by- event pT dispersion as a
function of multiplicity. A comparison of results shows distinct
differences in the behavior of the two samples as a function of the
center of mass energy. The properties of the soft sample are invariant as
a function of c.m. energy.

QCD events at sqrt(s) = 630 and 1800 GeV.

Transverse cone and 'Swiss cheese' underlying event studies

Authors:

Description:
This analysis studies the underlying event via transverse cones of $R =
0.7$ at 90 degrees in \phi relative to the leading (highest E) jet, at
sqrt(s) = 630 and 1800 GeV. This is similar to the 2001 CDF UE analysis,
except that cones, rather than the whole central \eta range are used. The
transverse cones are categorised as TransMIN and TransMAX on an event-by-
event basis, to give greater sensitivity to the UE component. 'Swiss
Cheese' distributions, where cones around the leading $n$ jets are
excluded from the distributions, are also included for $n = 2, 3$. This
analysis is useful for constraining the energy evolution of the
underlying event, since it performs the same analyses at two distinct CoM
energies. WARNING! The pT plots are normalised to raw number of events.
The min bias data have not been reproduced by MC, and are not recommended
for tuning.
Run details:
QCD events at sqrt(s) = 630 & 1800 GeV. Several pTmin cutoffs are
probably required to fill the profile histograms, e.g. 0 (min bias),
30, 90, 150 GeV at 1800 GeV, and 0 (min bias), 20, 90, 150 GeV at 630
GeV.

Authors:
Hendrik Hoeth
Description:
Rick Field's measurement of the underlying event in leading jet events.
If the leading jet of the event is within $|\eta| < 2$, the event is
accepted and ``toward'', ``away'' and ``transverse'' regions are defined
in the same way as in the original (2001) CDF underlying event analysis.
The leading jet defines the $\phi$ direction of the toward region. The
transverse regions are most sensitive to the underlying event.
Run details:
ppbar QCD interactions at 1960 GeV. Particles with $c \tau > {}$10 mm
should be set stable. Several $p_\perp^\text{min}$ cutoffs are
probably required to fill the profile histograms. $p_\perp^\text{min} =
{}$ 0 (min bias), 10, 20, 50, 100, 150 GeV. The corresponding merging
points are at $p_T = $ 0, 30, 50, 80, 130, 180 GeV

Description:
Deepak Kar and Rick Field's measurement of the underlying event in Drell-
Yan events. Z -> ee and Z -> $\mu\mu$ events are selected using a Z mass
window cut between 70 and 110 GeV. ``Toward'', ``away'' and
``transverse'' regions are defined in the same way as in the original
(2001) CDF underlying event analysis. The reconstructed Z defines the
$\phi$ direction of the toward region. The leptons are ignored after the
Z has been reconstructed. Thus the region most sensitive to the
underlying event is the toward region (the recoil jet is boosted into the
away region).
Run details:
* ppbar collisions at 1960 GeV. * Drell-Yan events with $Z/\gamma* -> e
e$ and $Z/\gamma* -> \mu\mu$. * A mass cut $m_{ll} > 70~\text{GeV}$ can

Description:
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.

0.7$ are included. For the transMIN and transMAX $\Delta(\phi)$ is
between $\pi/3$ and $2\pi/3$, and $\Delta(\eta) < 2.0$. For the jet
region the area of the jet is used for the normalization, i.e. the
scaling factor is $\pi R^2$ and not $\mathrm{d}\phi\mathrm{d}\eta$ (this
is different from what Rick Field does!). The tracking efficiency is
$\sim 0.8$, but that is an approximation, as below $pT \sim
0.6~\text{GeV}$ it is falling quite steeply.
