Abstract

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