TL;DR
In a simulated measurement of the W-boson mass, evaluation of Fisher's information shows the optimal jet definition to yield the same precision as the k(T) algorithm while being much faster at large multiplicities.
Abstract
In a simulated measurement of the $W$-boson mass, evaluation of Fisher's information shows the optimal jet definition to be physically equivalent to the $k_\mathrm{T}$ algorithm while being much faster at large multiplicities.
