TL;DR: In this article, the Monte Carlo event generator Herwig++ is used to simulate Hadron Emission Reactions with Interfering Gluons in electron-positron annihilation.
Abstract: Results from the new Monte Carlo event generator Herwig++ are pre- sented. This first version simulates Hadron Emission Reactions With Interfering Gluons in electron-positron annihilation. The parton shower evolution is carried out using new evolution variables suited to describing radiation from heavy quarks as well as light partons. The partonic final state is fragmented into hadrons by means of an improved cluster hadronization model. The results are compared with a wide variety of data from LEP and SLC.

TL;DR: In this article, the authors derived an analytical expression for the quenching factor in strong quench limit where the spectrum of hard partons is dominated by surface emission and explored the phenomenological consequences of different scaling laws for the energy loss and calculated the additional suppression of the away-side jet.
Abstract: We derive an analytical expression for the quenching factor in the strong quenching limit where the ${p}_{T}$ spectrum of hard partons is dominated by surface emission. We explore the phenomenological consequences of different scaling laws for the energy loss and calculate the additional suppression of the away-side jet.

TL;DR: In this paper, a new type-II model with fractal logical operators is presented, in which quasiparticle excitations are restricted to move along planes, lines, or not to move at all.
Abstract: Fracton phases are three dimensional topological phases in which quasiparticle excitations are restricted to move along planes, lines, or not to move at all. In this work, we show how such phases can be understood in terms of parton constructions, and in the process we find a new type-II model with fractal logical operators.

TL;DR: Open charm production during the equilibration of a gluon dominated parton plasma is calculated, with both the time-dependent temperature and parton densities given by a set of rate equations.
Abstract: Open charm production during the equilibration of a gluon dominated parton plasma is calculated, with both the time-dependent temperature and parton densities given by a set of rate equations. Including prethermal production, the total enhancement of open charm production over the initial gluon fusion depends sensitively on the initial parton density and the effective temperature. The dependence of the prethermal charm production on the space-momentum correlation in the initial parton phase-space distribution is also discussed.

TL;DR: In this article, the effects of cold nuclear matter effects on J / ψ production in proton-nucleus and nucleus-Nucleus collisions are evaluated taking into account the specific J/ ψ -production kinematics at the partonic level, the shadowing of the initial parton distributions and absorption in the nuclear matter.
