Query: Asymptotic Charges and Coherent States in QCD   We study the connection between asymptotic symmetries in non-Abelian gauge
theories and the generalised coherent states following from the application to
QCD of the Faddeev-Kulish approach to asymptotic dynamics. We compute the large
gauge transformation properties of the soft evolution operators and use this to
define the quantum corrected, non-linear contribution to the asymptotic
charges. We then compute the one-loop, leading IR-divergent, correction to
matrix elements of the charges inserted between dressed scattering states and
show that the results depend on a particular order of soft limits. For one
choice of ordering we find that the conservation law for the asymptotic charges
is not corrected, while for a second we find a correction proportional to the
one-loop soft current.
