  A scheme is proposed for calculating the entropy production in highly
transparent colliding systems. The formalism is continuum physical and fully
conform with thermodynamics; and the calculation is explicit in entropy
production. We have analyzed high energy heavy ion collisions from view point
of thermodynamics. Entropy densities are calculated for reactions up 14 TeV
energies. Final state particle productions are predicted using particle
generating quark and hadron models. We find that at LHC energy the entropy
density is 67.8. From this value we could predict particle yields, too. The
results show that there is not yet asymptotic freedom.
