Description
The propagation of hard partons through the strongly interacting matter
created in high energy heavy-ion collisions involves widely separated
scales. The methods of Effective Field Theories (EFT) can provide a
factorized description at lowest nontrivial order, and a formalism where
the correction to this factorization are calculable systematically order
by order in the small ratios between the different scales. In this talk
I will present our recent results on the calculation of the spectrum of
the gluons emitted by the hard parton, where the radiated gluons are
collinear with the incoming hard parton and with arbitrary energy (not
necessarily much softer than the energy of the hard parton). I will also
briefly discuss how to extend the analysis to include the emission of
gluons collinear in arbitrary directions and gluons with all the
components of their momentum scaling as the medium characteristic energy
scale (soft gluons).
