A primary problem for perturbative QCD analyses is how to set the renormalization scale of the QCD running coupling in order to achieve maximally precise fixed-order predictions for physical observables. The Principle of Maximum Conformality (PMC) eliminates the ambiguities associated with the conventional renormalization scale-setting procedure, giving predictions which are independent of the...

In the framework of soft-collinear effective theory with Glauber gluons, results and predictions for inclusive hadron suppression, based upon in-medium parton shower evolution, are presented for Au+Au and Pb+Pb collisions at RHIC and LHC energies, respectively. The SCETG medium-induced splitting kernels are further implemented to evaluate the attenuation of reconstructed jet cross in such...

Vacuum radiation of high-pT heavy quarks ceases at a short time scale, as is confirmed by LEP measurements of the fragmentation functions of heavy flavors. Production of a heavy flavored hadron is considerably delayed in a dense medium , what causes a strong suppression of the heavy quark yield in AA collisions in good accord with data.
