| Order parameters from persistent homology in non-Abelian gauge theory |
| Speaker: | Daniel Spitz (University Heidelberg) |
| Abstract: | Finding order parameters for the detection of critical phenomena and self-similar behavior in and out of equilibrium is a non-trivial endeavour in non-Abelian gauge theories. Tailored to detect topological structures in noisy data, recently both the sensitivity of persistent homology observables to equilibrium phase transitions as well as their suitability to describe far-from-equilibrium self-similar scaling have been demonstrated. In this talk I will provide an introduction to persistent homology, describe its application in SU(2) gauge theory in 3+1 dimensions, and use different filtrations by local energy densities or Polyakov loops computed from simulated field configurations to gauge-invariantly describe the confinement-deconfinement transition as well as reveal self-similar scaling in far-from-equilibrium scenarios. These results showcase the broad usability of persistent homology |

| Status Of The Future Circular Collider Feasibility Study |
| Speaker: | Michael Benedikt (CERN) |
| Abstract: | The Future Circular Collider (FCC) program, proposed at CERN, consists of a luminosity-frontier electron-positron collider (FCC-ee) as first stage, followed by an energy-frontier hadron collider (FCC-hh) as second stage, and promises the most far-reaching physics program for the post-LHC era. FCC-ee is a precision instrument to study the Z, W, Higgs and top particles, and oï¬ers unprecedented sensitivity to signs of new physics. Most of the FCC-ee infrastructure can later be reused for the subsequent hadron collider, FCC-hh. The FCC-hh provides proton-proton collisions at a centre-of-mass energy of 100 TeV and can directly produce new particles with masses of up to several tens of TeV.
The 2020 Update of the European Strategy requests a feasibility study of the FCC colliders and related infrastructure to be established as a global endeavor and completed on the timescale of the next Strat |
