Can anybody help me with this question?
If a trigger requires hits in some minimum number of layers when the whole setup com prises 12 detectors layers, what is the fraction of events that are recorded (as a function of this minimum number)?
These detectors typically have an efficiency of 90% to generate a hit when a particle passes through it. If you want to record the particle information at least half of the time, what should/could your trigger requirement be?
The search for this new particle requires the detection of two particles. How should you re-define your trigger to make sure you detect at least 50% of those?
