IFT MRs targeting August MD deadline

This branch collects new HLT2 IFT line updates aiming for the August Technical Stop (date: 24th July). It includes:

• Isolated photon lines: generic with a minimum pt (minpT) option. Lines to be added to the FULL stream. The dR=0.5 cone around the photon should have a total pT<0.2*minpT for isolation. Lines set with persistReco=True. Bandwidth tested on hlt1-filtered simulation, obtained 20 MB/s rates with the following line combinations :
  • Hlt2IFT_5GeVIsolatedGamma: minpT>5 GeV , prescale=0.01
  • Hlt2IFT_10GeVIsolatedGamma: minpT>10 GeV, prescale=0.1
  • Hlt2IFT_20GeVIsolatedGamma: minpT>20 GeV, prescale=1.0
• CEP lines for SMOG2. These are lines to trigger on Central Exclusive Production events produced in the SMOG2 cell in beam-empty bunch-crossings, where there is no activity from pp collisions with high-mu. Lines are discussed here: Moore !3667 (merged).
  • Rate and bandwidth in simulation might not be reliable, so bandwidth is estimated in data.
  • pHe+pp data from fill 9523, run 290437, used ~800k hlt1-filtered events (also estimated in pAr data, but rates are lower as hlt1 rate from cep line smaller)
  • Lines (rate in Hz indicated,
    • Hlt2IFTTURBO_SMOG2_CEP_1_TRACK (47+-7Hz), Hlt2IFTTURBO_SMOG2_CEP_2_TRACK (14+-4Hz), Hlt2IFTTURBO_SMOG2_CEP_3_TRACK (2.6+-1.8Hz), Hlt2IFTTURBO_SMOG2_CEP_4_TRACK (0Hz), Hlt2IFTTURBO_SMOG2_CEP_5_TRACK (0Hz): 1 to 5 long track lines
    • Hlt2IFTTURBO_SMOG2_CEP_2_MUON_TRACK (0Hz): dimuon line
    • Hlt2IFTTURBO_SMOG2_CEP_2_MUON_MIXED_TRACK (0Hz): muon and long track line (semileptonic decays and background studies)
  • Total bandwidth 0.082 Mb/s (driven by the low event size)
• Lines for pHe, which are already described and tested in the original merge request: !3279 (merged)
  • It has as dependencies: lhcb-datapkg/PRConfig!435 (merged) LHCbIntegrationTests!76 (merged) !3533 (merged) Rec!3955 (merged) LHCb!4579 (merged) Rec!3917 (merged) Rec!3855 (merged) LHCb!4512 (merged)
