536. Hyperasymptotic expansions in QCD

Plenary

We show how to apply hyperasymptotic expansions to QCD observables. This allows, in principle, to achieve exponential ($\sim exp (-1/\alpha)$) accuracy in their determination with a well defined parametric error. A selected set of applications we will discuss are heavy quark mass expansions, the static potential and the gluon condensate.

Plenary

The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN will significantly increase the collider's particle density, presenting new challenges for the ATLAS experiment's detectors. To address these challenges, a new radiation-hard beam monitoring system has been developed to protect the inner silicon detectors and accurately monitor the increased luminosity. This system...

499. Recent ALICE results on quarkonium

Plenary

ALICE (A Large Ion Collider Experiment) at the LHC aims at investigating the hot and dense QCD matter formed in ultra-relativistic heavy-ion collisions, and the transition to the Quark-Gluon Plasma (QGP). The suppression of charmonium and bottomonium states by color screening, and its hierarchy resulting from differences in binding energy, is a signature of QGP formation. Moreover, early...
