Top Quark Mass Calibration for Monte Carlo Event Generators
The most precise top quark mass measurements use kinematic reconstruction methods, determining the top mass parameter of a Monte Carlo event generator m$$MC\atop{t}$$. Because of hadronization and partonshower dynamics, relating m$$MC\atop{t}$$ to a field theory mass is difficult. Here, we present a calibration procedure to determine this relation using hadron level QCD predictions for observables with kinematic mass sensitivity. Fitting e ^{+}e ^{−}2jettiness calculations at nexttoleadinglogarithmic and nexttonexttoleadinglogarithmic order to PYTHIA 8.205, m$$MC\atop{t}$$ differs from the pole mass by 900 and 600 MeV, respectively, and agrees with the MSR mass within uncertainties, m$$MC\atop{t}$$ ≃ m$$MSR\atop{t,1 GeV}$$.
