All phase II analyses were recommended to move to prod 5 once processed.

Bernada talked on her analysis on B->D*lv with Phase II data. Similar results to existing analysis were seen in data. Will suggested to use MC10 instead of MC9 given that this has updated conditions specific to the actual running condtions achieved in phase II.

Christoph asked the lepton momentum cut and Bremsstrahlung effect. Kevin said  this is not included currently. Lu commented that the background leptons needs to be revisited after PID correction. William mentioned that KIT had developed a Bremsstrahlung recovery module for basf2.

Nadia presented the updates on FEI performance study including plots of tag-side efficiency vs purity. The specific FEI underperformed vs generic for hadronic tags in all cases for semileptonic tags for higher purities the specific FEI outperformed the generic FEI.
