Understanding the Impact of Pythia Hadronization in Top Quark Mass Determinations at the LHC : arXiv

Most of the methods to measure the top quarkmass suffer from the jet energy scaling in achieving better precision. As a way to circumvent this issue, the study of $B$- hadronobservables is motivated. While they do not involve such an issue, understanding underlying hadronizationmodels is a key to achieve $\sim 0.5\%$ precision or better. In this presentation, we discuss the impact of the hadronizationmodel parameters - for example, implemented in Pythia 8 - on precision measurements of the top quarkmass through $B$- hadronobservables. We study the sensitivity of the top quarkmass to relevant hadronizationand showeringparameters, followed by a discussion on observables to be used for constraining the hadronizationand showeringparameters.
