High-energy proton-nucleus (pA) collisions have provided various clues for
the role of cold nuclear matter effects in hadron production. In particular,
multiple rescatterings of an incoming parton by the nuclear target are known to
induce the radiation of many soft gluons, with those having a long formation
time leading to the modification of hadron production rates due to fully
coherent energy loss (FCEL). Here we present a recently derived formula for the
induced single soft gluon radiation spectrum beyond leading logarithmic
accuracy, whose main features are demonstrated with the example of $q\, g \to
q\, g$ scattering.
