Query: Model studies of fluctuations in the background for jets in heavy ion
  collisions   Jets produced in high energy heavy ion collisions are quenched by the
production of the quark gluon plasma. Measurements of these jets are influenced
by the methods used to suppress and subtract the large, fluctuating background
and the assumptions inherent in these methods. We compare the measurements of
the background in Pb+Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV by the ALICE
collaboration to calculations in TennGen (a data-driven random background
generator) and PYTHIA Angantyr. The standard deviation of the energy in random
cones in TennGen is approximately in agreement with the form predicted in the
ALICE paper, with deviations of 1-6 $\%$. The standard deviation of energy in
random cones in Angantyr exceeds the same predictions by approximately 40 $\%$.
Deviations in both models can be explained by the assumption that the single
particle $d^2N/dydp_T$ is a Gamma distribution in the derivation of the
prediction. This indicates that model comparisons are potentially sensitive to
the treatment of the background.
