We show that taking into account the interplay between perturbative and non-perturbative effects, the power-suppressed shift to the broadening distributions becomes B dependent, and the non-perturbative contribution to the mean values becomes proportional to 1/(Q\sqrt{\as(Q)}). The new theoretical treatment greatly improves the consistency of the phenomenology with the notion of the universality of confinement effects in jet shapes.

    The leading logarithmic correction to the 1/Q power correction for thrust and C-parameter is computed, with a sizeable coefficient S1 ≈ 2.455 and a universal C-to-thrust ratio of 3π/2.
