======================================== September 5th 2017 - Dilepton Z' search ======================================== Topics and questions: - Energy resolution of calorimeters, momentum resolution of trackers, consult PDG for details. - Which is the most significant detector for this search? The cal. or tracker? - What are some backgrounds for this search? What are the differences between the prompt and non-prompt backgrounds? Homework: - If, instead of Z', we were searching for the Z, would the cal. or tracker have better resolution for the measurement? If this is different to the Z', why? - One of the backgrounds in the Z' search is diboson production, which comes in 3 varieties: WW, WZ, ZZ. Why is the production involving W's more dominant that the one involving Z's? i.e WW > WZ > ZZ? Misc: - Textbook: I had a few questions about what testbook we're using in 226. It's Modern Particle Physics by Mark Thompson.
