I am always confused by the terminology:

In high energy particle scattering, and in particular, in the context of collider physics, what is the relationship between luminosity, intensity and flux? What are the (SI and natural) units for these quantities? And finally, how do they relate to the cross section and to the event rate?

There are so many quantities to keep track of--I think it's easy to get lost!!

Well... it looks like the wiki links that Qmechanic added to my question almost answers my question (especially the 'luminosity' link). I guess all that is left now is how to relate flux to the other two... – QuantumDot Aug 4 '12 at 19:07
