Back to basics: Wrong JES
{"Image DocumentName": "Back to basics: Wrong JES ?", "Image ImageDescription": "Not necessarily\u2026 Same effect is seen when looking at MC particle level\u2026 What is a jet ? For SSR. For the JES. Whole recoiling system to a \uf067/Z. R= 0.5 Particle jet. As said before (slides 5 et 6): The \uf044S observable, used to determine the SSR correction factors, is sensitive. to the rest of the event , QCD effects , out of cone radiation ,\u2026 Depends on the physics simulation ! This was observed by comparing MCs. for different processes (\uf067+jet and Z+jet) for different generators (ALPGEN and PYTHIA) Which is why Z+jet generated with ALPGEN was chosen as reference MC, as this is where SSR is most widely used. 29 Sept Christophe Ochando.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
