Abstract
The analyzing power A(N) in inclusive pi(-) and pi(+) production has b een measured with a 200 GeV/c transversely polarized antiproton beam o ver a wide x(f) range (0.2 less than or equal to x(f) less than or equ al to 0.9) and at moderate p(T) (0.2 less than or equal to p(T) less t han or equal to 1.5 GeV/c). The asymmetry A(N) increases with increasi ng x(F) from zero to large positive values for pi(-,)s, and decreases from zero to large negative values for pi(+,)s. A threshold for the on set of the asymmetry is observed about p(T) similar to 0.5 GeV/c, belo w which A(N) is essentially zero and above which A(N) increases (decre ases) with p(T) for pi(-,)s (pi(+,)s) in the covered p(T) range.
