- We call the resultant point ``an event'' in analogy to what
happens in real world. Monte Carlo Integrals are ``just''
averages over events. Call
- ``f'' = Cross-section to produce Higgs
- ``g'' = Particles interacting with experimental
detector.
- In the real world, each event has ``unit weight'' (God does
perfect importance sampling).
- In the Monte Carlo,
- g is typically 0 or 1, as it is in real world,
- f is a widely varying function reflecting
theoretical expectation (model).
- Calculating g is very time consuming as need to track many
(100's at SSC) particles through apparatus.
- Also, one typically has several different g's to calculate for
each f.
- These different g's are the responses of different parts of
apparatus.
