RDX run 1 validation: Phoebe vs us, 2011 MD

Info

The bold number with a link indicates that this number is consistent with a previous study, with the previous study linked.

If a number is bold but w/o a link, it shares the link for the number to its left.

\(D^*\), right-sign, Phoebe step-1+1.5 vs us

Note

  • Before the slanted step-1.5 line, the numbers are from Phoebe's step-1.
  • The * is considered immaterial
    • For Phoebe's ntuple, we remove the VELO only slow \(\pi\)
    • For us, this is already removed at DaVinci level

Info

  • It is known that PID and isolation BDT values have changed between DaVinci versions
  • Also, the vertexing has changed. This is manifested in the Offline \(D^* \mu\) combo cuts.
    • The cuts are defined in here.
    • Notably, we have vertex \(\chi^2/dof\) cuts, like b0_endvtx_chi2/b0_endvtx_ndof < 6.0.
