[PWGLF] dndeta-hi: move from PWGMM, add SD/DD/ND classification by hyungjun-lee · Pull Request #15779 · AliceO2Group/O2Physics

hyungjun-lee · 2026-04-15T08:15:21Z

Move dndeta-hi.cxx from PWGMM/Mult/Tasks to PWGLF/Tasks/GlobalEventProperties
Add kDD, kSD, kND enum values for diffractive event classification
Join McCollisions with HepMCXSections to access processId() in processMCCounting
Classify events by Pythia8 process code: 101=ND, 103/104=SD, 105/106=DD
Replace sliceByCached with sliceBy+Preslice for soa::Filtered tables
Fix std-prefix: std::log, std::exp, std::fabs
Fix const-ref-in-for-loop: const auto& in range-based for loops
Fix pdg/explicit-code: 310->kK0Short, 3122->kLambda0
Add CMakeLists.txt entry for dndeta-hi workflow

Hi @hyungjun-lee, can you please take care of o2-building error (https://ali-ci.cern.ch/alice-build-logs/AliceO2Group/O2Physics/15779/400b75d0b31bdf93b26a9e7717525813cfec57df/build_O2Physics_o2/pretty.html) by removing the line #include "Index.h"

Thanks,
Abhi

hyungjun-lee · 2026-04-15T09:10:08Z

The remaining o2linter error originates from code outside of my responsibility. Could you please approve this commit?

abmodak · 2026-04-15T09:14:07Z

Hello @hyungjun-lee, I talked about the O2-building errors (not the linter error). But anyway, you fixed it, thanks!
I will approve the PR once all the required checks will be finished.

Thanks,
Abhi
