Documentation

The selection is described in detail in this public lhcb note (2007).

DC06 Jun production

The DC06 data have been processed with the standard selection (DVSelB2HH), producing microDST files.

• The signal production has been done using DaVinci v19r12
• Selection from PhysSel/B2uds v2r6p2

Brunel v31 stripping data

That have been selected from the Bookkeping using the tag: DC06-Stripping-v31-lumi2.

This data sample has been processed with this opts file: the Tagging and Trigger algorithms were enabled and copied to the microDST.

Brunel v30 signal MC jobs

• microDST have been produced with the options attached having added the Tagging algorithm...
• Input data is:
  • 1272746 Bd to Kpi evts: BdKpi.opts and BdKpi_2.opts
  • 1317096 Bd to pipi evts: Bdpipi.opts and Bdpipi_2.opts
  • 22862 Bs to KK evts: BsKK.opts
  • 129216 Bs to Kpi evts: BsKpi.opts
• The microDST produced are available in the castor area. You can use the opts files attached here to access them...

Tools for data access

• A gaudi python script can be used to dump the info need for the B2hh (simultaneous) fit
