This note describes the use of the Bootstrap in a High Energy Physics experiment. A typical experiment [1] in this field might involve collection of 100 million “events”, (collisions of subnuclear particles) each described by 1K-500K Bytes of information. Each of these events must be analyzed to deduce the kinds of particles involved. One step in this analysis is discussed here; this particular example involves the identification of high energy γ rays (photons), which produce narrow “showers” in one of our detector. The problem is to distinguish these from another particle, called a π°, which decays into two photons and thus produces a slightly wider shower in our detectors.
