The issue

Changed:
<
<
In order to obtain an unbiased (or less biased) measure of the displacement of a particle wrt a PV (eg, flight distance, decay time, etc), PVs must be refitted excluding the signal tracks. This is enabled by setting ReFitPVs = True on the appropriate algorithm (CombineParticles, FilterDesktop, etc). However, in order to trigger the generation of refitted PVs, the PVs must be accessed by the algorithm, eg, by a BPV* LoKi functor. When refitted PVs are generated, they are saved to the output mDST along with the particle $\rightarrow$ PV relations tables and so are accessible for user analysis. If the refitted PVs aren't generated, they can't be recovered offline on the mDST Turbo output.

This is enabled by setting ReFitPVs = True on the appropriate algorithm (CombineParticles, FilterDesktop, etc). However, in order to trigger the generation of refitted PVs, the PVs must be accessed by the algorithm, eg, by a BPV *

LoKi functor. When refitted PVs are generated, they are saved to the output mDST along with the particle $\rightarrow$ PV relations tables and so are accessible for user analysis. If the refitted PVs aren't generated, they can't be recovered offline on the mDST Turbo output.

  The majority of Turbo lines requesting PV refitting in some algorithm in their sequence didn't do so in conjunction with a BPV functor, and so the refitted PVs aren't persisted, and are lost.

These are lines that requested PV refitting in some way, but did it incorrectly. Many of these include some $\mathrm{IP} \chi^2$ cuts, which will mitigate the effect, so these are also listed.

Systematic checks

If you care about PV refitting and you're using an affected line:

Changed:
<
<
  • Firstly, check the $\mathrm{IP} \chi^2$ distribution of the tracks in your data. If their minimum values are all > 9 then you should be safe.
>
>
  • Firstly, check the $\mathrm{IP} \chi^2$ distribution of the tracks in your data. If their minimum values are all > 9 then you should be safe.
 
  • If you have full DST MC for your analysis you can check if the daughter tracks are ever included in the PV fit. Note that the PVs are constructed from HLT1 fitted VELO tracks, so you'll have to unpack these tracks and compare by LHCbIDs to your signal tracks. You can also evaluate the effect of refitting the PVs excluding signal tracks.
  • Try tightening the displacement cuts ($\mathrm{IP} \chi^2$, $\mathrm{FD} \chi^2$, decay time, etc) in your selection and examine how your results vary.
  • Apply a cut on PV n. tracks and vary its value. The greater the number of tracks in the PV, the less influence your signal candidate will have on the PV.
