Abstract
Yields for production in collisions at have been measured over the rapidity range and compared with results in and collisions at the same energy. The data offer greatly improved precision over existing data for production in collisions with small to intermediate numbers of participants, in the range where the quark-gluon plasma transition threshold is predicted to lie. Cold nuclear matter estimates based on ad hoc fits to data describe the data up to , corresponding to a Bjorken energy density of at least .
