Title: Single spin asymmetries of inclusive hadrons produced in electron scattering from a transversely polarized 3 He target

We report the first measurement of target single-spin asymmetries (A N) in the inclusive hadron production reaction, e + 3He↑→h+X, using a transversely polarized 3 He target. This experiment was conducted at Jefferson Lab in Hall A using a 5.9-GeV electron beam. Three types of hadrons (π ±, K ± and proton) were detected in the transverse hadron momentum range 0.54 < p T < 0.74 GeV/c. The range of x F for pions was -0.29 < x F< -0.23 and for kaons -0.25 < x F<-0.18. The observed asymmetry strongly depends on the type of hadron. A positive asymmetry is observed for π + and K +. A negative asymmetry is observed for π–. The magnitudes of the asymmetries follow |A π |<|A π +|<|A K +|. The K and proton asymmetries are consistent with zero within the experimental uncertainties. The π + and π asymmetries measured for the 3He target and extracted for neutrons are opposite in sign with a small increase observed as a function of p T.
