      abstract     = {Event generators like Pythia play an important role in
                      physics studies at the Large Hadron Collider (LHC). While
                      they make accurate predictions in the central region, i.e.
                      at pseudorapidities $\eta<5$, a disagreement between Pythia
                      and measurements in the forward region, $\eta>7$, has been
                      observed. We introduce a dedicated forward physics tune for
                      the Pythia event generator to be used for forward physics
                      studies at the LHC, which uses a more flexible modelling of
                      beam remnant hadronization and is tuned to available
                      particle spectra measured by LHCf. Furthermore, we provide
                      an uncertainty estimate on the new tune in a data-driven way
                      which can be used as a means of flux uncertainty for future
                      forward physics studies. We demonstrate an application of
                      our tune by showing the updated neutrino and dark photon
                      spectra at the FASER experiment.},
