In this study, a factorization framework was developed to compute the double differential cross section in soft drop groomed jet mass and groomed jet radius, with a description of effective theories in different groomed jet radius regions. The NLL ' results for perturbative moments relating to hadronization corrections were presented, and compared with Monte Carlo simulations and a calculation using the coherent branching method.
We develop a factorization framework to compute the double differential cross section in soft drop groomed jet mass and groomed jet radius. We describe the effective theories in the large, intermediate, and small groomed jet radius regions defined by the interplay of the jet mass and the groomed jet radius measurement. As an application we present the NLL ' results for the perturbative moments that are related to the coefficients C-1 and C-2 that specify the leading hadronization corrections up to three universal parameters. We compare our results with Monte Carlo simulations and a calculation using the coherent branching method.
