  1. FCC software tutorial OUTLINE Pythia stand alone ROOT with PYTHIA8 Pythia with Delphes Examples PID 1 FCC tutorial, Pisa April 2021 F. Bedeschi, INFN-Pisa

  2. PYTHIA Main site: http://home.thep.lu.se/~torbjorn/Pythia.html Installation in dir/ wget http://home.thep.lu.se/~torbjorn/pythia8/pythia8304.tgz tar xzvf pythia8304.tgz cd pythia8304 ./configure --enable-shared --prefix=dir/pythia8304 make install (warning: libpythia8.so is created and deleted!) export PYTHIA8=dir/pythia8304 export PYTHIA8DATA=$PYTHIA8/share/Pythia8/xmldoc 2 FCC tutorial, Pisa April 2021 F. Bedeschi, INFN-Pisa

  3. root_build root_install && root_build -- -j4 cmake --build ROOT with Pythia8 Need recent version of ROOT 6 mkdir ROOT && cd ROOT git clone --branch v6-22-00-patches https://github.com/root- project/root.git root_src mkdir root_build root_install && cd root_build cmake -DCMAKE_INSTALL_PREFIX=$HOME/ROOT/root_install - DPYTHIA8_DIR=$PYTHIA8 - DPYTHIA8_INCLUDE_DIR=$PYTHIA8/include - DPYTHIA8_LIBRARY=$PYTHIA8/lib/libpythia8.so -Dbuiltin_xrootd=ON -Droofit=ON -Dpythia8=ON ../root_src cmake --build . -- install -j4 source ../root_install/bin/thisroot.sh .. GOOD LUCK (docker: rootproject/root-archlinux) 3 FCC tutorial, Pisa April 2021 F. Bedeschi, INFN-Pisa

  4. Play with PYTHIA Run standalone Pythia8 from ROOT Run and write out events example Pytha configuration example: config_ee_zh_Hmumu.cmd Root>.L pythia_HmmWrite_example.c+ pythia_HmmWrite_example(Nev, Out.root ) Read back and analyze Root>.L pythia_HmmRead_example.c+ Root> HmmRead(Nev, Out.root ) 4 FCC tutorial, Pisa April 2021 F. Bedeschi, INFN-Pisa

  5. DELPHES (1) Do not need to link ROOT with Pythia8 to run DELPHES Build DELPHES ($PYTHIA8 defined): git clone https://github.com/delphes/delphes.git cd delphes ./configure make HAS_PYTHIA8=true -j4 To rebuild after changes: make clean ./configure make HAS_PYTHIA8=true j4 5 FCC tutorial, Pisa April 2021 F. Bedeschi, INFN-Pisa
