Next-to-leading-logarithm threshold resummation for exclusive B meson decays
European Physical Journal C: Particles and Fields, 2021 We extend the threshold resummation of the large logarithms $$\ln x$$ ln x which appear in factorization formulas for exclusive B meson decays, x being a spectator momentum fraction, to the next-to-leading-logarithm (NLL) accuracy.

Mellin Transforms of Whittaker Functions [PDF]
Canadian Mathematical Bulletin, 2002 AbstractIn this note we show that for an arbitrary reductive Lie group and any admissible irreducible Banach representation the Mellin transforms of Whittaker functions extend to meromorphic functions. We locate the possible poles and show that they always lie along translates of walls of Weyl chambers.

Light transformed gluon correlators in CCFT
Journal of High Energy Physics, 2023 In the present work, we study celestial correlators of light transformed gluon operators at tree level. We also discuss the transformation of light transformed operators under the action of 4D translations. The two, three and four-point functions arising

GKZ-hypergeometric systems for Feynman integrals
Nuclear Physics B, 2020 Basing on the systems of linear partial differential equations derived from Mellin-Barnes representations and Miller's transformation, we obtain GKZ-hypergeometric systems of one-loop self energy, one-loop triangle, two-loop vacuum, and two-loop sunset ...

Transformation de Mellin: aspects numériques et dérivation fractionnaire. Application aux lois des variables aléatoires positives. [PDF]
, 1999 Le châtoiement qui caractérise les images de Radar à Synthèse d'Ouverture (RSO) est un bruit multiplicatif. La transformation de Mellin, moins populaire que la transformation de Fourier, est cependant mieux adaptée au traitement de ce type d'images.
