18. + = 0. [18] Since our Fock-space expansion will be truncated to just quark pairs, the results will not depend on whether or not we retain antiparticles in the mode expansion. This is done to eliminate kinematical regimes not under consideration, from the start.

32. m. Thus one is always guaranteed that less transversal momentum will flow through the wave functions for physical ξ that are large enough.
33. ⊥. That means the factorization breaking present in these models has nothing to do with the amplification of the SPD as we approach maximal skewness (cf. Fig. 5 where no factorization breaking is discernable but maximal skewness amplification certainly occurs).
