Abstract: Many collider observables suffer from non-global logarithms not captured by standard resummation techniques. Classic examples are the light-jet mass distribution. In this talk I will introduce our recent work about factorization formulas for the non-global observables, and explicitly demonstrate that they capture all logarithms present at Next-to-Next-to-Leading Order. These formulas achieve full scale separation and provide the basis for all-order resummation. Numerically, the contributions of non-global logarithms to resummed non-global observables are sizeable.
