    abstract = "The effect of event background fluctuations on charged particle jet
reconstruction in Pb-Pb collisions at root s(NN) = 2.76 TeV has been
measured with the ALICE experiment. The main sources of non-statistical
fluctuations are characterized based purely on experimental data with an
unbiased method, as well as by using single high p(t) particles and
simulated jets embedded into real Pb-Pb events and reconstructed with
the anti-k(t) jet finder. The influence of a low transverse momentum
cut-off on particles used in the jet reconstruction is quantified by
varying the minimum track p(t) between 0.15 GeV/c and 2 GeV/c. For
embedded jets reconstructed from charged particles with p(t) > 0.15
GeV/c, the uncertainty in the reconstructed jet transverse momentum due
to the heavy-ion background is measured to be 11.3 GeV/c (standard
deviation) for the 10% most central Pb-Pb collisions, slightly larger
than the value of 11.0 GeV/c measured using the unbiased method. For a
higher particle transverse momentum threshold of 2 GeV/c, which will
generate a stronger bias towards hard fragmentation in the jet finding
process, the standard deviation of the fluctuations in the reconstructed
jet transverse momentum is reduced to 4.8-5.0 GeV/c for the 10% most
central events. A non-Gaussian tail of the momentum uncertainty is
observed and its impact on the reconstructed jet spectrum is evaluated
for varying particle momentum thresholds, by folding the measured
fluctuations with steeply falling spectra."
