  We present analytical calculations of the distribution of non-global jet
shapes in Higgs/vector boson + jet production at hadron colliders. Within the
eikonal-limit framework and implementing various jet algorithms, we compute the
full distribution of the particular jet mass shape observable at 2-loops,
including the large single-logarithms known as non-global logs and clustering
logs. We compare our next-to-leading-log analytical resummation to parton
showers and, after matching and including non-perturbative effects, to
experimental data. A good agreement is shown for all comparisons.
