Production and ratio of $\pi$, K, p and $\Lambda$ in Pb + Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV

S. Zhang, L. X. Han, Y. G. Ma +2

The particle production and their ratios for $\pi$, $K$, $p$, and $\Lambda$ are studied in Pb + Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV based on a blast-wave model with thermal equilib…
