DESCRIPTION:Speakers: Kamel Khelifa-Kerfa (Université Hassiba Benbouali d
e Chlef)\nWe present a general formalism for computing the matrix-elements
squared for the emission of soft energy-ordered gluons to (theoretically)
any order in perturbation theory at finite $N_c$. Our formalism is valid
in the eikonal approximation. A Mathematica package is being developed for
the automated calculation of all real/virtual eikonal squared-amplitudes
necessary at a given order. For the purpose of illustration we show the ex
plicit forms of the eikonal amplitudes up to the fifth order. In the large
-$N_c$ limit our results coincide with those previously reported in litera
ture.\n\nhttps://indico.cern.ch/event/341292/contributions/1739095/
