Abstract: Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polarization. The asymmetry depends on the azimuthal angles of both the pion (phi) and the target spin axis (phi(S)) about the virtual-photon direction and relative to the lepton scattering plane. The extracted Fourier component sin((phi+phi(S))(pi)(UT) is a signal of the previously unmeasured quark transversity distribution, in conjuncti… Show more

“…Experimental evidence for a nonzero Collins function was found by the HERMES [12,13] and COMPASS [14,15] Collaborations, from the analysis of semi-inclusive deep inelastic scattering (SIDIS) of leptons off transversely polarized hydrogen and/or deuteron targets. The cross sections for these processes are proportional to the convolution of the Collins function and the chiral-odd transversity function [16].…”

“…Knowledge on transversity is a cornerstone for further exploring the 3D structure of nucleon and provides a fundamental test on QCD. So far, the semiinclusive deep inelastic scattering (SIDIS) data offer the most accessible/promising way to probe transversity [3,4,5,6,7,8,9]. However, global fit is needed here to decouple the convoluted CFF and transversity, so the input from the independent measurements of the CFF at e + e − experiment is necessary [10].…”
