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.
