Abstract
We report the measurement of beam-target double spin asymmetries (A LT) in the inclusive production of identified hadrons, e + 3 He → h + X, using a longitudinally polarized 5.9-GeV electron beam and a transversely polarized He 3 target. Hadrons (π ±, K ±, and proton) were detected at 16 with an average momentum P h = 2.35 GeV/c and a transverse momentum (p T) coverage from 0.60 to 0.68 GeV/c. Asymmetries from the He 3 target were observed to be nonzero for π ± production when the target was polarized transversely in the horizontal plane. The π + and π - asymmetries have opposite signs, analogous to the behavior of A LT in semi-inclusive deep-inelastic scattering.
