Abstract

We perform the leading logarithmic resummation of nonglobal logarithms for the single-hemisphere jet mass distribution in $e^+e^-$ annihilation including the finite- $N_c$ corrections. The result is compared with the previous all-order result in the large- $N_c$ limit as well as fixed-order perturbative calculations.
