[PWGHF] Hadron Table Update for Event Mixing and High-p T Electron Cut by rashigupt · Pull Request #16112 · AliceO2Group/O2Physics

rashigupt · 2026-05-05T08:33:00Z

Implemented changes to save the hadron table for offline event mixing in correlatorHfeHadron.cxx and added a high-(p_T) cut in the electron selection in `ElectronSelectionWithTPCEMCal.cxx.

Dear Expert, if everything looks okay, please approve and merge the code.

Dear Rashi,
with offline ME, we usually refer to the computation of the ME distributions completely offline, as explained in this presentation.
I am not entirely sure that what you want to do with this process function will work, since you may be limited to mixing hfe and hadrons that belong to the same DF.
(In case you want to use the same strategy as other analyses, close this PR.)

+      for (const auto& hadron : hadrons) {

Suggested change

if (electron.timeStamp() == hadron.timeStamp()) {

if (electron.timeStamp() == hadron.timeStamp() && hadron.gIndexCol() == electron.gIndexCol()) {

+        if (hadron.gIndexCol() == electron.gIndexCol()) {
