Description

I will discuss recent advances in resummation of observables for probing the substructure of jets. By grooming the jet with soft drop, non-global logarithms in the jet mass can be removed. Extending the factorization theorem for soft drop jet mass, we are able to calculate the distribution of $D_2$, an observable that is sensitive to two-prong structure in the jet. The soft dropped $D_2$ distribution is remarkably robust: we show that it is approximately independent of jet energy, non-perturbative corrections are suppressed by the jet mass, and fixed-order corrections can be formally made arbitrarily small.
