Prospects for strong coupling measurement at hadron colliders using soft-drop jet mass

Abstract

We compute the soft-drop jet-mass distribution from $pp$ collisions to NNLL accuracy while including nonperturbative corrections through a field-theory based formalism. Using these calculations, we assess the theoretical uncertainties on an ${\alpha }_s$ precision measurement due to higher order perturbative effects, nonperturbative corrections, and PDF uncertainty. We identify which soft-drop parameters are well-suited for measuring ${\alpha }_s$, and find that higher-logarithmic resummation has a qualitatively important effect on the shape of the jet-mass distribution. We find that quark jets and gluon jets have similar sensitivity to ${\alpha }_s$, and emphasize that experimentally distinguishing quark and gluon jets is not required for an ${\alpha }_s$ measurement. We conclude that measuring ${\alpha }_s$ to the 10% level is feasible now, and with improvements in theory a 5% level measurement is possible. Getting down to the 1% level to be competitive with other state-of-the-art measurements will be challenging.
