1. Regular items
o The open requirements, pending actions, status of long open bug reports, as well as physics and computing performance monitoring are reviewed.
o ATLAS observed a 3% -4% shift of the EM sampling fraction from 9.6 to 10.2 while our validation suite shows a stability at the per mil level. A preliminary study indicates this is related to very thin layers surrounding the absorber and the effect could be reproducible by our tests. Further studies are ongoing.
o About 5% computing performance degradation was observed from ref-03 to ref-04 for INCL++ and BIC tests. Further studies are ongoing.
2. Spokesperson election
o The Election Management Team reported 81 vote casts (71% of eligible collaborators) during the vote period of April 1st though 18th, and the tally was 76 yeses and 5 abstains.
o The election process and the result were endorsed.
o Makoto Asai (Spokesperson) and Marc Verderi (Deputy Spokesperson) have a new two-year term.
o The Steering Board appreciates the Election Management Team, Alex Howard, Ivana Hrivnacova and Peter Gumplinger, and tally taker Dr. Oliver Grimm.
