QCD jets produced from colliding two heavy nuclei play
an important role in understanding properties of the Quark Gluon Plasma pr
oduced in these energetic collisions. During their travel through the medi
um\, high energy partons lose their energy due to interactions with the me
dium through elastic collisions and medium-induced splitting processes lik
e bremsstrahlung and pair production. In the high energy limit\, these spl
itting processes are coherent over large distances and can no longer be tr
eated as quantum mechanically independent\, leading to a suppression of th
e splitting rate known as the Landau-Pomeranchuk-Migdal effect. An importa
nt question that arises is whether consecutive splittings of the high ener
gy particle overlap within the formation time of an individual splitting.
This case has been analyzed in the *N*_{c} = &infin\; limit
within the thick medium approximation. To see if this result applies for
real QCD with *N*_{c} = 3\, we calculate the next to leadin
g order correction (i.e. O(1/*N*^{2})) to the gluon double-
splitting. We have already completed a subset of the diagrams known as *sequential* diagrams. In this talk\, I will report first results on w
hether the *N*_{c} = &infin\; \; approximation to the d
ifferential rate of overlapping double bremsstrahlung of gluons is reliabl
e\, and in particular whether the correction is large or small compared to
the naive expectation of 1/*N*2c \;_{c} = 3.
