Query: Hadronic observables from a hadronic rescattering model in $Pb+Pb$
  collisions at $\sqrt{s_{NN}}=2.76$ TeV   We employ a simple kinematic model based on the superposition of $p+p$
collisions, relativistic kinematics, and final-state hadronic rescattering to
calculate a number of hadronic observables in $\sqrt{s_{NN}}=2.76$ TeV $Pb+Pb$
collisions. The current model is similar to those used in previous studies, but
includes an additional procedure ("squeeze procedure") which modifies the model
pseudorapidity distribution to better represent the experimental data. In
addition, we vary the model hadronization time ($\tau$ = 0.1, 0.2, 0.3 fm/c) to
gain a better understanding of our systematic uncertainty. We find that the
simple model describes the overall data reasonably well qualitatively, and in
some cases quantitatively. Furthermore, the model is found to be robust in the
sense that using the squeeze procedure and small variations of the
hadronization proper time do not significantly affect our results.
