DelphesMA5tuneIsolationCalculation Module
This module is designed for calculations related to isolating and tuning simulations in Delphes and MadAnalysis 5. It provides tools for fine-tuning isolation parameters, enhancing efficiency in analysis workflows. The module streamlines the process of isolating signals and backgrounds, offering precise control over isolation settings and optimization strategies. With its advanced algorithms and functions, users can achieve accurate isolation calculations and improve the overall performance of their physics analyses.

DelphesMA5tune IsolationCalculation module
Gridpacks produced @ IIHE have been transferred to Strasbourg. Instructions are reported in a wiki https://sbgcmswikidoc.in2p3.fr/doku.php?id=topfcnc_copy Goal: validate the production step1+step2+step3 for the exclusive production ZToLL50 and WToLNu. Some gridpacks were missing: 0 jet 1 jet 2 jet 3 jet 4 jet ZToLL50 No Ok Ok No Ok WToNLu No Ok Ok Ok Ok Cross sections for each contribution has been computed.
Exclusive production of ZToLL50 - status: 0 jet 1 jet 2 jet 3 jet 4 jet Gridpack Ok Ok Ok Ok Ok LHE Ok Ok Ok Problem ? Running ROOT Ok Ok Ok Running Number of generated events != Number of expected events Convergence issue Solutions: We can live with this problem. Only ~60% expected events are produced. Try to help MadGraph. Example: splitting the specified process into several sub-processes: P13_gg_llgqq P13_gq_llggq P13_qq_llggg P13_gq_llqqq P13_qq_llgqq
Exclusive production of ZToLL50 - status: 0 jet 1 jet 2 jet 3 jet 4 jet Gridpack Ok Ok Ok Ok Ok LHE Ok Ok Ok Problem ? Running ROOT Ok Ok Ok Running ME/PS merging validation plots with contribution of 0,1,2 extra jets. Going well
Exclusive production of WToLNu - status: 0 jet 1 jet 2 jet 3 jet 4 jet Gridpack Ok Ok Ok Ok Ok LHE Ok Ok Ok Ok running ROOT Ok Ok Ok OK ME/PS merging validation plots with contribution of 0,1,2 extra jets. Going well
To do: Finish all the steps Try to split the ZToLL50-3 jets into several subprocesses. Making the final ME/PS merging validation plot Validating quickly the ROOT samples with MadAnalysis: Cross-check the value of event-weights Smoothness of the jet PT spectrum Typical observable such ass Mll, MT(W),
Another point to understand: merging configuration within Pythia for exclusive production "Min jet" and "Max jet" parameters should be set. My naive idea Done by CMS and used here Contribution Minjet Maxjet Contribution Minjet Maxjet 0 jet 0 4 0 jet 0 99 1 jet 0 4 1 jet 1 99 2 jet 0 4 2 jet 2 99 3 jet 0 4 3 jet 3 99 4 jet 0 4 4 jet 4 4
