The signature-changing soft-gluon term as a possible source of non-planar $ζ_{2}$ terms at small $x$ in the non-singlet quark-plus-antiquark splitting function

Olasantan Ebenezer Adelaja, Alex Prygarin, Claudelle Capasia Madjuogang Sandeu

A relation underlying resummations at small momentum fraction $x$ predicts the highest logarithms of quark-plus-antiquark flavor-difference splitting functions from lower orders. C…

Lévy structure of the forward fixed-coupling BFKL kernel and a fixed-order obstruction to positivity in the symmetric scheme

Alex Prygarin, Claudelle Capasia Madjuogang Sandeu, Karam Shekh Yusuf

We establish a Levy interpretation of normalized forward BFKL small- $x$ evolution at leading order and fixed coupling, and exclude a probability law at fixed-order next-to-leading…

Higher-order local constraints from reciprocal symmetry and entanglement entropy of charged-particle multiplicity distributions in $pp$ collisions

Mustapha Ouchen, Alex Prygarin, Claudelle Capasia Madjuogang Sandeu

The KNO-violating term $f_{s}$ of the charged-particle multiplicity distribution in $pp$ collisions measures the relative deviation of $⟨ n ⟩ P_{n}$ from $e^{- z}$ , with $z=n…
