“…Finding an exactly solvable example of llsi is another desideratum. It is conceivable that the logarithmic terms found in the scaling function in the simple phenomenological scheme proposed here are but the first few terms of an infinite logarithmic series, perhaps in analogy to ideas raised long ago in [38,39]. Of course, further independent tests of the proposal presented here would be desirable.…”

Ageing phenomena far from equilibrium naturally present dynamical scaling and in many situations this may generalised to local scale-invariance. Generically, the absence of time-translation-invariance implies that each scaling operator is characterised by two independent scaling dimensions. Building on analogies with logarithmic conformal invariance and logarithmic Schrödinger-invariance, this work proposes a logarithmic extension of local scale-invariance, without time-translation-invariance. Carrying this out requires in general to replace both scaling dimensions of each scaling operator by Jordan cells. Co-variant two-point functions are derived for the most simple case of a two-dimensional logarithmic extension. Their form is compared to simulational data for autoresponse functions in several universality classes of non-equilibrium ageing phenomena.

“…Nor is any further reference or argument provided, and it is not at all clear what the definitions of the parton distributions are. It should also be noted that in [25], an axial gauge is used for studying the leading graphs of high-p T processes. Thus one would here again expect the problems mentioned above that stem from unphysical gauge singularities.…”

Fundamental to much work in small-x QCD is a kT -factorization formula. Normal expectations in theoretical physics are that when such a result is used, citations should be given to where the formula is justified. We demonstrate by examining the chains of citations back from current work that violations of this expectation are widespread, to the extent that following the citation chains, we do not find a proof or other justification of the formula. This shows a substantial deficit in the reproducibility of a phenomenologically important area of research. Since the published formulae differ in normalization, we test them by making a derivation in a simple model that obeys the assumptions that are stated in the literature to be the basis of kT -factorization in the small-x regime. We find that we disagree with two of the standard normalizations.
