Update SMOG2 KS trackeff lines in Turcal
This MR aims to add some updates and improvements to the Ks->pipi tracking efficiency lines using the VELO-Long method with Ks candidates coming from SMOG2. They mostly follow what is already in the equivalent lines for pp (https://gitlab.cern.ch/lhcb/Moore/-/blob/master/Hlt/Hlt2Conf/python/Hlt2Conf/lines/trackeff/KSVeloLong.py?ref_type=heads).
To do:
-
Add tis filter for HLT1 unbiasing -
Add selective persistency of matched track -
Remove RAW banks (not needed with selective persistency) -
Readjust selection to reduce background and improve kinematic converage, update prescales -
Unifiy code with KSVeloLong (with pp lines, following Sasha and Laurent suggestion) -
Remove Long track containers (keep only MatchedLongPions and MatchedUpstreamPions) -
Test new Bandwidht with SMOG2 data, compare with previous one (expect a reduction thanks to moving to Turbo strategy) -
Check if I need to change the line names, or if further changes are needed in hlt2/sprucing sequence
Local Bandwidth tests results (on a representative pp+pAr sample from Block 1, the same as in !4500 (merged) ). Note that this data is from block 1 (mu pp 4.4), so the SMOG2 bandwidth is representative while the bandwidth of pp lines should be below that one in mu=5.3 conditions.
