DESCRIPTION:Speakers: Tim Harris (ETH Zürich)\n\nCorrelation functions of
  conserved currents play an important role in the Standard Model. For exam
 ple\, hadronic vacuum polarization enters in precision determinations of t
 he muon's anomalous magnetic moment and electroweak precision tests\, and 
 whose uncertainty is dominated by the low-energy non-perturbative regime. 
 Lattice QCD estimates have reached the precision where the QED corrections
  cannot be neglected. In this talk I will discuss a programme using the fr
 amework of C* (or C-periodic) boundary conditions to include such effects 
 on a finite lattice in a way consistent with locality and gauge invariance
 . In another phase at extreme temperatures\, correlators of conserved curr
 ents parameterize interesting in-medium processes and collective behaviour
 . I will outline a new approach to constrain some thermal production rates
  which are relevant for heavy-ion collision phenomenology. While a quantit
 ative description is still challenging\, the methodology required for futu
 re progress has significant overlap with precision computations.\n\nhttps:
