RE: Citizen science on Hive - detector effects and event reconstruction

[travelingmercies]

Excited to do this task as I clear up some of my tasks at work. Briefly read the post and I just want to ask this question for clarification..

The software installed in the first week, MadGraph5_aMC@NLO, is used to simulate collisions? And the MadAnalysis5 tool is used for the analysis of the generated signal? I often see MadAnalysis5 in the publications linked from your previous blog posts. :) I thought it was the same with MadGraph5_aMC@NLO.

Great! I am looking forward to read your report :)

These are two different packages, whose developers are good friends on top of being colleagues :)

MG5aMC allows us to simulate the core hard process (the most energetic part of the collision). Pythia 8 is steered by MG5aMC and allow to add on this the simulation of the strongly-interacting environment of the LHC. From there, we switch to MadAalysis5 for the simulation of the detector effects, the reconstruction of the events and their analysis.

Does it clarify the role of each component of this chain of tools?

I was able to complete this set of tasks for the project. 🤩 I did encounter a problem on the default version of Python my terminal uses (macOS has pre-installed Python2) and I had to set Python3 as the default version to fix this problem.

There are packages set as DISABLED by default, however in this tutorial, there were set as DISABLED BY THE USER. I am a bit confused between these two, or on how will a package not disabled will affect the analysis? (the image below shows Root marked with [OK] instead of [DISABLED BY THE USER], alongside this, Root was used as the package for graphical rendering). From what I understood, you have mentioned that this detail is irrelevant?

I went on and continue with the tasks and still was able to produce the expected distribution plot:

I'll write about these on my report, detailing all these I mentioned. Thanks and I enjoyed this set of tasks! :)

I had to manually disable those package because they are available system-wide on my computer. I had decided that it would be better to show them disabled by myself than available (because they would be otherwise available what ever I do). In any case, having them or not does not matter. So you are good to go.

Congrats for obtaining the plot. I am now looking forward to read the report :)

Yes! I get the big picture now. :) Will this chain of tools and the flow you've discussed above compose the methodology part of the project?

[lemouth]

Definitely!
