  Particle production in central Pb-Pb collisions at LHC is discussed in the
context of the Statistical Model. Predictions of various particle ratios are
presented with the corresponding choice of model parameters made according to
the systematics extracted from heavy-ion collisions at lower energies. The
sensitivity of several ratios on the temperature and the baryon chemical
potential is studied in detail, and some of them, which are particularly
appropriate to determine the chemical freeze-out point experimentally, are
indicated. We show that the anti-p / p ratio is most suitable to determine the
baryon chemical potential while the Omega / K and Omega / pi ratios are best to
determine the temperature at chemical freeze-out.
