Oral presentation slides: title toc global problem - what problem will you solve - understanding of QCD, emphasis on LHC physics - Use Z + jets to study perturbative regiem at high energies as well as low energy non-perturbative QCD LHC + CMS Improving Hcal and DAQ with the AMC13 2016 Dataset What phase space to do this measurement What MC to compare to for different QCD models Analysis details - non-resonant backgrounds, Unfolding Results Future plans - obvious route of more data, wont help in a lot of places - need better MC predictions both in uncertainty and models To Do: - Put rapidity labels on double differential ratio plots - May want to make a third intro slide with the specifics on the Z (Saying things like: proxy for how well we do in the non-preturbative regime) - Potentially some more result slides (dependent on the timed runs)
