661“…To this end, we investigate the sensitivity of the top-quark mass, determined by means of a few observables already proposed in the literature as well as some new proposals, to the relevant parameters of event generators, such as HERWIG 6 and PYTHIA 8. We find that constraining those parameters at O(1%–10%) is required to avoid a Monte Carlo uncertainty on mt greater than 500 MeV. …”

T., Wichmann, K., Wing, M., Yamada, S., Yamazaki, Y., Żarnecki, A.F., Zenaiev, O.“…For the multiplicities studied, neither the measurements in photoproduction processes nor those in neutral current deep inelastic scattering indicate significant collective behaviour of the kind observed in high-multiplicity hadronic collisions at RHIC and the LHC. Comparisons of PYTHIA predictions with the measurements in photoproduction strongly indicate the presence of multiparton interactions from hadronic fluctuations of the exchanged photon.…”

664por Cyburt, Richard H., Ellis, John R., Fields, Brian D., Olive, Keith A., Spanos, Vassilis C.“…We calculate the dominant two- and three-body decays of both neutralino and stau NSPs, and model the electromagnetic and hadronic decay products using the PYTHIA event generator and a cascade equation. Generically, the introduction of bound states drives light element abundances further from their observed values; however, for small regions of parameter space bound state effects can bring lithium abundances in particular in better accord with observations. …”
