| Title | Single Spin Asymmetries of Inclusive Hadrons Produced in Electron Scattering from a Transversely Polarized 3He Target | ||||
| Abstract | We report the first measurement of target single-spin asymmetries (AN) in the inclusive hadron production reaction, e+3He??h+X, using a transversely polarized 3He target at an electron-nucleon center-of-mass energy s {sqrt} =3.45 GeV. The experiment was conducted at Jefferson Lab in Hall A using a 5.9-GeV electron beam. Three types of hadrons (pi +/-, K+/- and proton) were detected with an average momentum <Ph>=2.35 GeV/c, and an average transverse momentum <pT>=0.64 GeV/c. The observed asymmetry strongly depends on the type of hadron. A positive asymmetry is observed for ?+ and K+. A negative asymmetry is observed for pi-. The magnitudes of the asymmetries follow |Api-|<|Api+|<|AK+|. The K- and proton asymmetries are consistent with zero within the experimental uncertainties. The pi+ and pi- asymmetries measured for the 3He target and extracted for neutrons are opposite in sign with a small increase observed as a function of pT. | ||||
