On threshold resummation of the longitudinal structure function
Georges Grunberg
The validity of a previously proposed momentum space ansatz for threshold resummation of the non-singlet longitudinal structure function F_L is checked against existing finite orde…
On threshold resummation beyond leading 1-x order
G. Grunberg, V. Ravindran
We check against exact finite order three-loop results for the non-singlet F_2 and F_3 structure functions the validity of a class of momentum space ansaetze for threshold resummat…
Threshold resummation to any order in (1-x)
Georges Grunberg
A simple ansatz is suggested for the structure of threshold resummation of the momentum space physical evolution kernels (`physical anomalous dimensions') at all orders in (1-x), t…
A dispersive approach to Sudakov resummation
Einan Gardi, Georges Grunberg
We present a general all-order formulation of Sudakov resummation in QCD in terms of dispersion integrals. We show that the Sudakov exponent can be written as a dispersion integral…
Dispersive approach in Sudakov resummation
Georges Grunberg
The dispersive approach to power corrections is given a precise implementation, valid beyond single gluon exchange, in the framework of Sudakov resummation for deep inelastic scatt…
Infrared finite coupling in Sudakov resummation: the precise set-up
Georges Grunberg
I show that Sudakov resummation takes a transparent form if one deals with the second logarithmic derivative of the short distance coefficient functions for deep inelastic scatteri…
