[PWGCF] FemtoUniverse -- adiing KK invariant mass, adding everything to a new process function by zchochul · Pull Request #18588 · AliceO2Group/O2Physics

zchochul · 2026-11-04T14:06:41Z

New process function was created, because this part of the code turned out to be more costly then expected on resources and the analysis was unable to run on Hyperloop. In this approach, I am doing everything in a separate process function. The code used before can be easily not used with a configurable and as discussed this is a work-around, I plan to come back to the previous version (with the configurable) whenever I am able to solve this issue.

I had very helpful guidance from @vkucera for this PR. Thank you, Vit!
