    • A Dispersive approach to Sudakov resummation. 

      Gardi, Einan; Grunberg, Georges (High Energy Physics, Cavendish Laboratory, University of Cambridge, 2007-09)
      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 over spectral density functions, weighted ...
