Query: Canonical Strangeness and Distillation Effects in Hadron Production   Strangeness canonical ensemble for Maxwell-Boltzmann statistics is
reconsidered for excited nuclear systems with non-vanishing net strangeness. A
new recurrence relation method is applied to find the partition function. The
method is first generalized to the case of quantum strangeness canonical
ensemble. Uncertainties in calculation of the K+/pi+ excitation function are
discussed. A new scenario based on the strangeness distillation effect is put
forward for a possible explanation of anomalous strangeness production observed
at the bombarding energy near 30 AGeV. The peaked maximum in the K+/pi+ ratio
is considered as a sign of the critical end-point reached in evolution of the
system rather than a latent heat jump emerging from the onset of the first
order deconfinement phase transition.
