Workflow for MC

  • Make your tuples.
  • Preselection in the Selection folder. This applies minimal things but it will collate your tuples. It also calculates the angles and $q^{2}$. You should be able to start from the tuples produced here subsequently.
  • Apply PID resampling in the PID PID_sampling folder.
  • Apply the L0 emulation, TISTOS weights and tracking efficiency correction weights with the apply_weights.py script in the track_eff folder.
  • Apply final selection in the Final_Selection folder. This adds the BDT and does most of the selection, including vetoes and (corrected) PID.
  • If you are doing the $J/\psi K^{*}$ MC, then you also need to add the S-wave weights with the script in the S-wave folder.
  • Apply kinematic reweighting with the python script in kinematic_reweighter . This will apply the L0 efficiency weights and the tracking correction.

Acceptance

  • All the code is in the Acceptance folder. Should be fairly self explanatory.
Optimum orders:
Sample $q^2$ range O($\cos{\theta_l}$) O($\cos{\theta_K}$) O($\phi$) O($q^2$) O($m_{K\pi}$)

Workflow for data

  • Make your tuples.
  • Preselection in the Selection folder. This adds the BDT and applies most of the cuts. NOTE: It does not apply a cut on the BDT or L0!
  • Use perform_mass_cuts macro to apply the necessary mass cuts to make the rare-mode / $J/\psi$ samples.

Notes

  • The best fit value to the published LHCb analysis, using all variables, is: $C_{9}=-1.027$, $C_{10}=0.498$
  • The best fit value to the published LHCb analysis using only the P variables is: $C_{9}=-0.970$, $C_{10}=0.324$
