RD: Add Xib2XiGamma DDL and DDD trigger line
Adding DDL and DDD trigger lines for the Xib- -> (Xi- -> (Lambda -> p pi) pi) Gamma decay.
These two lines are expected to benefit from our recent improvements of having the HLT1 downstream trigger lines.
BW test results: Overall +0.1MB/s
-
Hlt2RD_XibmToXimGamma_XimToL0Pim_DDLDecision: 0.000113 GB/s -
Hlt2RD_XibmToXimGamma_XimToL0Pim_DDDDecision: 0.000155 GB/s
For comparison, our baseline
Hlt2RD_XibmToXimGamma_XimToL0Pim_LLLDecision gives 0.000308 GB/s.
Selection efficiency:
-
Hlt2RD_XibmToXimGamma_XimToL0Pim_DDLDecision: 33% -
Hlt2RD_XibmToXimGamma_XimToL0Pim_DDDDecision: 31%
The baseline LLLDecision line gives 32% efficiency but is prescaled to 0.1, resulting in an effective efficiency of only 3%.
Note: Efficiency = (number_of_selected) / (number_of_reconstructed), requiring BKG_CAT=0.
Running over the same amount of signal MC, the number of candidates passing the trigger lines is:
-
LLLDecision: 16 -
DDLDecision: 440 -
DDDDecision: 1120
