Description of the line

Hlt2 lines for B0-->KS0l+l-, B+-->KS0pi+l+l- and Lb0-->L0l+l- decays for both LL and DD KS0s and L0s, based on the Thor rd_builders and l+l- is mu+mu-, e+e- and mu+e-.

These lines essentially port over the stripping cuts used in Run 1 and Run 2 to select these lines, with soft PID requirements on the electrons and muons (PIDe / PIDmu > 0).

MC samples used in the development

1. Minbias: upgrade_minbias_hlt1_filtered
2. Upgrade signal MC for B0-->KS0l+l-, B+-->KS0pi+l+l- and Lb0-->L0l+l- but no mu+e- samples

Hi Harry, thanks a lot for this work! Do you have a bit more specific information on the efficiency per signal mode? (and are those efficiencies relative to HLT1 or not?) It could be interesting to see if there are large variations there. Thanks in advance!
