A brief overview of properties the model quantized fragmentation a helical QCD string is followed by discussion colour reconnection models and ways to reproduce evolution average transverse momentum in hadronic events, as function charged particle multiplicity. Reference recent experimental data included.
The quantum properties of a helixlike shaped QCD string are studied in the context semiclassical Lund fragmentation model. It is shown how simple quantization rules combined with causality considerations process describe mass hierarchy light pseudoscalar mesons. quantized helix model predicts observable effects related to threshold behavior intrinsic transverse momentum hadrons, and minimal difference between adjacent hadrons. numerical fit field breaking into ground state hadrons agree...
Previous studies of the physics potential LEP2 indicated that with design luminosity 500 inverse picobarn one may get a direct measurement mass W-boson precision in range 30 - 50 MeV. This report presents an updated evaluation estimated error on based recent simulation work and improved theoretical input. The most efficient experimental methods which will be used are also described.
This document collects the proceedings of "Parton Radiation and Fragmentation from LHC to FCC-ee" workshop (http://indico.cern.ch/e/ee\_jets16) held at CERN in Nov. 2016. The writeup reviews latest theoretical experimental developments on parton radiation parton-hadron fragmentation studies --including analyses LEP, B-factories, data-- with a focus future perspectives reacheable $e^+e^-$ measurements Future Circular Collider (FCC-ee), multi-ab$^{-1}$ integrated luminosities yielding...
The properties of a helix-like shaped QCD string are studied in the context Lund fragmentation model, where concept 3-dimensional structure gluon field offers an alternative aproach to modelling transverse momentum hadrons. paper is focused on phenomenology which introduces correlations between and longitudinal components hadrons, as well azimuthal ordering hadrons along string. similarities 2-particle stemming from helix-string those commonly attributed Bose-Einstein interference pointed...
Baryon production is studied within the framework of quantized fragmentation QCD string. Baryons appear in model a fairly intuitive way, with help causally connected string breakups. A simple helical approximation flux tube parameters constrained by mass spectrum light mesons sufficient to reproduce masses baryons.
Correlations between charged particles provide important insight into the hadronization process. The analysis of momentum difference hadrons in pp, p-lead, and lead-lead collisions at LHC is performed by ATLAS Collaboration order to study dynamics hadron formation. spectra correlated chains are explored compared predictions based on quantized fragmentation a three dimensional QCD helix string. This provides an alternative view two-particle correlation phenomenon typically attributed...
The causal view of hadron formation allows to establish a simple quantization scheme describing mass spectra light hadrons. resulting model predicts multitude observable effects, notably the enhanced production close pairs equally charged pions, traditionally attributed Bose-Einstein interference. Model predictions agree with measurements performed by ATLAS Collaboration.

Inclusive measurement of J/Ψ (DELPHI), search for η b (ALEPH) and the cross-section double-tagged γγ events are briefly overviewed.
A simple quantization concept for a 3-dim QCD string is used to derive properties of flux tube from the mass spectrum light mesons and predict observable quantum effects in correlations between adjacent hadrons. The quantized fragmentation model presented compared with experimental observations.
An alternative model of the fragmentation Lund string, investigating hypothesis helix-like ordered gluon field, is compared with hadronic $Z^0$ data. A significant improvement in description various measured quantities achieved. In particular, existence correlations between longitudinal and transverse components hadron momenta (as suggested by helix string model) seems to be supported
The experimentally observed enhancement of number close boson pairs in e+e- collisions is reproduced by local weighting according to the quantum mechanical prescriptions for production identical bosons. space-time picture process, inherently present Lund fragmentation model, explicitly used. model used check systematic errors W mass measurements due Bose-Einstein effect. possibility direct implementation effect into string discussed.

A critical summary is given of the present status study Bose-Einstein Correlations in W-pair production at LEP II. In particular, evidence reviewed for or against existence correlations between pions originating both from a different two W's. If present, such an inter-W interference would not only form potential bias determination W mass, but also provide laboratory to measure space-time development overlap. absent, this drastically change conventional (Hanbury Brown and Twiss) picture pion...
The study of the quantization QCD string with helix structure is put into context a decades-long discussion opposing probabilistic and deterministic interpretations quantum theory. recent evolution fragmentation model (to large extent driven confirmed by empirical evidence), towards point view recounted: notion causality not only paves way to mass spectrum, it also resolves long-standing ambiguity about nature so-called Bose-Einstein correlations. Two directions for further development are...
In this proceedings contribution, we review recent calculations of the dynamics chromo-Weibel instability in quark-gluon plasma.This is present gauge theories which possess a one-particle distribution function which, local rest frame, momentum-space anisotropic.The conditions necessary for triggering can be already color-glass-condensate initial state or dynamically generated by rapid longitudinal expansion matter created heavyion collision.Using hard-loop framework, study case that...
