Abstract
OpenAlex · English
Abstract New sets of parameter tunes for two of the colour reconnection models, quantum chromodynamics-inspired and gluon-move, implemented in the pythia 8 event generator, are obtained based on the default CMS pythia 8 underlying-event tune, CP5. Measurements sensitive to the underlying event performed by the CMS experiment at centre-of-mass energies $$\sqrt{s}=7$$ s = 7 and 13 $$\,\text {Te\hspace{-.08em}V}$$ Te V , and by the CDF experiment at 1.96 $$\,\text {Te\hspace{-.08em}V}$$ Te V are used to constrain the parameters of colour reconnection models and multiple-parton interactions simultaneously. The new colour reconnection tunes are compared with various measurements at 1.96, 7, 8, and 13 $$\,\text {Te\hspace{-.08em}V}$$ Te V including measurements of the underlying-event, strange-particle multiplicities, jet substructure observables, jet shapes, and colour flow in top quark pair ( $${{\text {t}} {}{\bar{\text {t}}}}$$ t t ¯ ) events. The new tunes are also used to estimate the uncertainty related to colour reconnection modelling in the top quark mass measurement using the decay products of $${{\text {t}} {}{\bar{\text {t}}}}$$ t t ¯ events in the semileptonic channel at 13 $$\,\text {Te\hspace{-.08em}V}$$ Te V .
