Abstract
We present ratios of the numbers of charged antihadrons to hadrons (pions, kaons, and protons) in collisions at as a function of rapidity in the range . While the ratios at midrapidity are approaching unity, the and ratios decrease significantly at forward rapidities. An interpretation of the results within the statistical model indicates a reduction of the baryon chemical potential from at to at .
