Are there monojets in high-energy proton-nucleus collisions?

We study high-energy proton-nucleus collisions within the colour glass condensate framework, and compute the probabilities of having a definite number of scatterings in the nucleus with a momentum transfer larger than a given cut. Various properties of the distribution in the number of multiple scatterings are investigated, and we conclude that events in which a monojet is equilibrated by many soft recoiling particles at a close rapidity are very unlikely, except for extreme values of the saturation scale Q(s).
