Trigger Configuration Key (TCK)

  • This TWiki explains briefly how to use TCKsh to study TCKs.
  • This starter kit page provides some sample usage for TCKsh
  • This page has all TCK info for LHCb.

    Note

    This link have .pdf files that list all TCKs for a given period of time.

    For example, in the 2016 year-end report:

    • All TCKs in this period, such as 0x1138160E, are listed in page 6.
    • TCK vs. fill number are listed in page 18. The fill number is related to time, but the relationship is unknown to us1.

Find particle masses used by the LoKi functors

The full mass table for a particular DaVinci version can be looked up with2:

lb-run DaVinci/<dv_version> dump_particle_properties | tee ParticleTable.txt

Alternatively, the latest mass table is available at cern-gitlab

Notes on pidcalib2

A guide to pidcalib2 can be found here.

usage of --cut and --pid-cut

Say pidcalib2 is invoked like this:

lb-conda pidcalib pidcalib2.make_eff_hists \
    --cut "A" --cut "B" \
    --pid-cut "PA" --pid-cut "PB"

Then 2 histograms will be generated, with the following efficiencies:

  1. \(\epsilon_1 = \frac{N(\text{A & B & PA})}{N(\text{A & B})}\)
  2. \(\epsilon_2 = \frac{N(\text{A & B & PB})}{N(\text{A & B})}\)

Note that all cuts supplied in all --cut flags are all applied first.
