Discoveries and Upper Limits

  • Luca Lista
Part of the Lecture Notes in Physics book series (LNP, volume 941)


The goal of many experiments is to search for new physical phenomena. If an experiment provides a convincing measurement of a new signal, the result should be published and claimed as discovery. If the outcome is not sufficiently convincing, in many cases it is nonetheless interesting to quote, as the result of the search for the new phenomena, an upper limit to the yield of the new signal. From upper limits to the signal yield, it is often possible to indirectly derive limits on the properties of the new signal. Limits could be set to the mass of a new particle or to coupling constants; more in general, it’s possible to exclude regions of the parameter space of a new theory that influences the signal yield.
