Description
JEWEL is a fully dynamical event generator for jet evolution in a dense
QCD medium, which has been validated for multiple jet and jet-like
observables. Jet constituents (partons) undergo collisions with thermal
partons from the medium, leading to both elastic and radiative energy
loss. The recoiling medium scattering centres carry away energy and
momentum from the jet. Keeping track of these recoils is essential for
the description of intra-jet observables. Since the thermal component of
the recoils is part of the soft background activity, comparison with
data on jet observables requires the implementation of a background
subtraction procedure. We will show two independent procedures through
which background subtraction can be performed and discuss the impact of
the medium recoil on jet shape observables and jet-background
correlations. Keeping track of the medium recoil significantly improves
the JEWEL description of jet shape measurements.
