      Speakers: Antoine Laudrain (FTX (FTX Fachgruppe DTA)), Benno List (IPP (Info-management Prozesse u. Projekte)), Carl Mikael Berggren (FTX (FTX Fachgruppe SLB)), Christian Schwanenberger (DESY, University of Hamburg), Christophe Grojean (T (Theorie)), Frank Gaede (FTX (FTX Fachgruppe SFT)), Jenny List (FTX (FTX-SLB)), Juergen Reuter (DESY), Dr Karsten Buesser (DESY), Ties Behnke (DESY)
      • Accelerator:
        • Benno asks Beate again. Probably co-ordination with Wim / M needed.
      • Generator:
        • Juergen: much clearer picture on problem with Pythia interface:  Whizard should apply only the (relative) beam-spectrum boost, but not the one between the asymmetric lab frame and the nominal ECM
        • crossing angle: should stay with event generation head-on plus lateral boost in simulation, as this corresponds to the crab-crossing situtation.
      • GuineaPig: see slides
        • next Antoine will check pairs
        • if all comparisons between C and C++ version turn out ok, then should move to C++ completely
      • Lumi measurement
        • consider ee->ee and ee->yy 
        • is SuperKEKB / Belle-II and example for lumimeasurement at asym collider? Not really, since they get ~1% precision, not 10^-4..5
        • once we understand the e+e- pair distributions, we need to involve FCal / Ivanka at some point...
