  One-point correlators of conserved charges are argued to be perturbatively IR
safe in QCD, which includes not only the density of energy, but also those of
electric charge, isospin and baryon number. Theoretical and phenomenological
aspects of the density matrix of one-point correlators are discussed in the
context of the states produced by a chiral current, as in the decay of a
polarized electroweak boson. Densities of some non-conserved charges such as
energy with arbitrary non-negative powers, despite their incalculability, are
shown to obey an infinite set of consistency constraints. QCD is observed to
live near a kink in the allowed parameter space of one-point correlators.
