The signature-changing soft-gluon term as a possible source of non-planar terms at small 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 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- evolution at leading order and fixed coupling, and exclude a probability law at fixed-order next-to-leading…
The next-to-next-to-leading order BFKL eigenvalue at odd conformal spin in planar N=4 super Yang-Mills: a reconstructed closed form, coefficient structure, and arithmetic
Alexander Prygarin, Claudelle Capasia Madjuogang Sandeu
We give the colour-singlet eigenvalue of the three-loop BFKL kernel of planar N=4 super Yang-Mills in closed form at odd conformal spin n. It splits into a holomorphic block and it…
The next-to-next-to-leading order BFKL eigenvalue at odd conformal spin in planar N=4 super Yang-Mills
Alexander Prygarin, Claudelle Capasia Madjuogang Sandeu
We give the next-to-next-to-leading order color-singlet BFKL eigenvalue of planar N=4 super Yang-Mills at odd conformal spin n in closed form. At the two lower orders the known exp…
Higher-order local constraints from reciprocal symmetry and entanglement entropy of charged-particle multiplicity distributions in collisions
Mustapha Ouchen, Alex Prygarin, Claudelle Capasia Madjuogang Sandeu
The KNO-violating term of the charged-particle multiplicity distribution in collisions measures the relative deviation of from , with $z=n…
