TL;DR: In this paper, the results for the differential distributions of jets from non-leptonic decays of polarized top quarks within the Standard Model, including QCD radiative corrections, were presented.

TL;DR: In this article, the authors studied the fragmentation of arbitrary parton configurations, with particular emphasis on events where two partons have a small invariant mass, and formulated an explicit model for the fragmentation process.

TL;DR: A new release of the Monte Carlo event generator Herwig (version 7.2) is now available, which introduces a number of improvements over the major version 7.0, notably multi-jet merging with the dipole shower at LO and NLO QCD and spin correlations in both the dipoles and angular-ordered parton showers.
Abstract: A new release of the Monte Carlo event generator Herwig (version 7.2) is now available. This version introduces a number of improvements over the major version 7.0, notably: multi-jet merging with the dipole shower at LO and NLO QCD; spin correlations in both the dipole and angular-ordered parton showers; an improved choice of evolution variable in the angular-ordered parton shower; improvements to mass effects and top decays in the dipole shower, improvements to the simulation of multiple-parton interactions, including diffractive processes; a new model for baryonic colour reconnection; improvements to strangeness production; as well as a new tune of the hadronisation parameters and support for generic Lorentz structures in BSM models. This article illustrates new features of versions 7.1 and 7.2.

TL;DR: Using a multiphase transport model that includes both initial partonic and final hadronic interactions, the pion interferometry at the Relativistic Heavy-Ion Collider is studied and it is found that the two-pion correlation function is sensitive to the magnitude of the parton-scattering cross section.
Abstract: Using a multiphase transport model that includes both initial partonic and final hadronic interactions, we study the pion interferometry at the Relativistic Heavy-Ion Collider. We find that the two-pion correlation function is sensitive to the magnitude of the parton-scattering cross section, which controls the parton density at which the transition from the partonic to hadronic matter occurs. Also, the emission source of pions is non-Gaussian, leading to source radii that can be more than twice larger than the radius parameters extracted from a Gaussian fit to the correlation function.

TL;DR: In this paper, a proposal is made, giving multiparticle (parton) spectra inside quark and gluon jets in terms of the tree diagrams of an effective field theory.
