Precise definition of jet energy scale and jet energy resolution Is it correct to say that jet energy scale is only related to Monte Carlo simulations? I can't seem to find a pedagogical introduction about these things that states it properly.
 A: I'm not actually a high-energy guy, and my knowledge of jets is all second hand, but I did do a graduate summer school on the topic one year. If I recall correctly...

*Jet energy is the total energy of particles making up the jet.

*Jet energy resolution is the experimental limit on how well that quantity can be known.
You'll note that both of these automatically depend on your jet identification scheme.

The reason you're not finding a lot of pedagogical material is that little of it is published. The state of the art in analysis moves fast, and any book will be obsolete with in months of hitting the shelves. None the less there are still a few. I used Perkins and Leo in grad school, but they are fairly dated by now.
Worse, the detailed meaning of these quantities can vary slightly from collaboration to collaboration. That is the algorithm used to compute the quantities is not set in stone, but exists as a nebulous set of expectations and practices, which each groups adapts to the details of the experiment. Exception: I believe that competing experiments at the same facility (i.e. CDF and D0 at the Tevatron or CMS and Atlas at LHC) collaborate to make sure that their definitions are comparable.
