“…--HTML-->Event generators have largely been used for central physics predictions at the LHC and parameters regarding hadron production in these generators have been tuned using central physics data. In particular, Pythia has proven to be a reliable generator for central measurements, but it's prediction for forward particle production shows disagreement with LHCf data, which points to a need for a Pythia tune for the FPF. …”
