Measurement of Single-spin Asymmetry in Charged Kaon Electroproduction on a Transversely Polarized $^{3}$He Target

Data on target single-spin asymmetry in the semi-inclusive deep inelastic $\vec{n}(e,e'K^{\pm})X$ reaction have been taken in Hall A at Jefferson Lab using a transversely polarized $^3$He target and an electron beam of 5.9 GeV. This measurement covers the kinematic region, $x = 0.13\sim 0.41$, at $Q^2=1.3\sim 3.1~ (\mathrm{GeV}/c)^2$. In coincidence with the scattered electrons detected in the large-acceptance BigBite spectrometer, kaons were detected in the high-resolution spectrometer and identified using an aerogel Cherenkov, gas Cherenkov and Ring-Imaging Cherenkov (RICH) detectors together with time-of-flight (TOF) information. The kaon single-spin asymmetry data from this experiment are expected to provide constraints on the flavor dependence of the transversity and the Sivers distribution functions. Results on the kaon single-spin asymmetry will be presented and compared with theoretical calculations.
