“…with X being a triplet, antisixplet or fifteenplet. Since the final states in these three processes are distinct, we can express all the quark fragmentation functions for the hadron h in terms of the independent fragmentation probabilities α(x, Q), β(x, Q), and γ(x, Q) where α (β, γ) is the fragmentation probability when X = 3 (6,15). The corresponding probabilities for antiquark fragmentation are α, β and γ (in this case, there is an antitriplet fragmenting into an octet and X, with the X being a 3,6 or 15).…”

SU(3) model for octet baryon and meson fragmentation

1998

The production of the octet of baryons and mesons in e + e − collisions is analysed, based on considerations of SU(3) symmetry and a simple model for SU(3) symmetry breaking in fragmentation functions. All fragmentation functions, D h q (x, Q 2 ), describing the fragmentation of quarks into a member of the baryon octet (and similarly for fragmentation into members of the meson octet) are expressed in terms of three SU(3) symmetric functions, α(x, Q 2 ), β(x, Q 2 ), and γ(x, Q 2 ). With the introduction of an SU(3) breaking parameter, λ, the model is successful in describing hadroproduction data at the Z pole. The fragmentation functions are then evolved using leading order evolution equations and good fits to currently available data at 34 GeV and at 161 GeV are obtained.

“…For the calorimetric measurement, the largest source of systematic uncertainty is the difference between the efficiencies derived from the three simulations (Table 5.1). In contrast to [122], where the most important error arises from the choice of using either Jetset or Herwig for the determination of the efficiencies, here the largest difference is observed between the two samples generated using the two different Jetset samples tuned to OPAL data [123] and [124]. Notable differences between the two Jetset samples are the inclusion of L = 1 mesons [123], consequent changes to the ω and η rates by factors of 1.5 and 4.5, respectively and the version of the detector simulation program [125].…”

Coherence Effects and Perturbative QCD Tests with the OPAL Detector at LEP

I report on results and methods from a set of analyses performed within the OPAL collaboration at CERN. The full available data sample collected at and near the Z0 resonance is used. Results concern colour‐field interference and coherence phenomena, quark and gluon jet properties, identified particles in quark and gluon jets, measurements of the QCD colour factors and relevant tests of recently improved perturbative QCD calculations. The challenge is that QCD is a quantum field theory that requires all orders in perturbation theory and non‐perturbative analysis to confront data at available energies. Thus, precise measurements can be thought as explorations of quantum field theory itself. Nonetheless, these tests and measurements have important practical applications, in the calculation of backgrounds to new physics and, for hadron collider particularly, in predictions for new particle cross‐sections.
