derstanding properties of the Quark Gluon Plasma. During their travel through
the medium, high energy partons lose energy through splitting processes like
bremsstrahlung and pair production, induced by elastic scatterings with the
medium. In the high energy limit, these splitting processes are coherent over
large distances and the underlying elastic scatterings can no longer be treated
as quantum mechanically independent, leading to a suppression of the splitting
rate known as the Landau-Pomeranchuk-Migdal effect. An important question
is whether consecutive splittings are themselves quantum mechanically indepen-
dent or instead overlap significantly. Previously, the overlap of splitting rates
has been calculated in the soft bremsstrahlung limit and it was found that such
corrections are large but can be absorbed by accounting for similar corrections
to a qˆ parameter that characterises properties of the medium. Since we now
have the QCD calculations required, we can answer the refined question: how
big are the corrections to shower development due to overlapping formation
times that cannot be absorbed into an effective value of qˆ ?
