Yes. Well done!

This is, indeed, #ifdef SELECTRON an event containing an electron. #endif #ifdef SMUON an event containing a muon. #endif #ifdef SHADRON an event containing a hadron. #endif #ifdef ELECTRON an electron pair event. #endif #ifdef MUON an muon pair event. #endif #ifdef TAU an tau pair event. #endif #ifdef QUARK an quark pair event. #endif #ifdef LNULNU a WW (lepton-neutrino/lepton-neutrino) event. #endif #ifdef QQQQ a WW (four quark) event. #endif #ifdef ENUQQ a WW (electron-neutrino/two quark) event. #endif #ifdef MUNUQQ a WW (muon-neutrino/two quark) event. #endif #ifdef TAUNUQQ a WW (tau-neutrino/two quark) event. #endif #ifdef LLGAM an llgamma event. #endif #ifdef QQGAM an qqgamma event. #endif #ifdef QQG an qqg event. #endif #ifdef FFFF a "four fermion" event #endif
