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…
