Draft: Seeding p tuning
Previous versions of the tuning rely on parameterisations that mix topological (i.e. choice of first layers) and kinematical (i.e. choice of momentum for which cases are optimised) information.
This change reformulates the two-hit and three-hit search windows in a way that is faster (~12% fewer calls), although with lower efficiencies, but also makes the choice of layers & minimum momentum explicit. There are still some momentum dependencies hidden in the U/V search, but the effect is believed to be less important. Such change allows to change the order of layers and/or momentum thresholds.
Also, the number of parameters for the X search goes from 27 to around 12.
This MR also provides two new pieces of code:
- PrAlgorithms/tools/PrHybridSeedingTuner.cpp: it allows to produce out of a .digi sample a lot of variables used in the tuning
- PrAlgorithms/tools/produceTuning.py: this is the code that produces, out of the output of PrHybridSeedingTuner, some variables related to the seeding.
I aim at presenting this at RTA WP2 meeting, and a link to the presentation will be added to this text when done.
Todo:
- [] p/pt efficiency plots: do we care about the tracks we're missing?
- [] test on more various physics channels (e.g. KS)
-
line fit in the tuner -
cubic fit in the tuner -
dRatio tuner
