Hi guys, I have some general questions and was hoping some of you might be able to answer them.
Does anyone know what it means to be "collinear unsafe" and "infrared unstable" when referring to energy reconstruction in calorimeters?
Also why do theorist prefer collinear and infrared safe data?
Why does is infrared- and collinear-safety to all orders of perturbative QCD?
