نویسنده
چکیده
Presented here is a technique of propagating uncertainties through the parton shower by means of an alternate event weight. This technique provides a mechanism to systematically quantify the effect of variations of certain components of the parton shower leading to a novel approach to probing the physics implemented in a parton shower code and understanding its limitations. Further, this approach can be applied to a large class of parton shower algorithms and requires no changes to the underlying implementation.

The dynamics in QCD with different number of fermion flavors N f is discussed. The emphasis is on the description of the conformal phase transition with respect to N f separating a phase with no confinement and chiral symmetry breaking and a phase with confinement and with chiral symmetry breaking.

The propagation of hard partons through spatially extended matter leads to medium-modifications of their fragmentation pattern. Here, we review the current status of calculations of the corresponding medium-induced gluon radiation, and how this radiation affects hadronic observables at collider energies.
