Measurement of Transverse Spin Effects at COMPASS
Abstract
By measuring transverse single spin asymmetries one has access to the transversity distribution function T q(x) and the transverse momentum dependent Sivers function q0T(x,kT). New measurements from identified hadrons and hadron pairs, produced in deep inelastic scattering of a transversely polarized 6LiD target are presented. The data were taken in 2003 and 2004 by the COMPASS collaboration using the muon beam of the CERN SPS at 160 GeV/c, resulting in small asymmetries.
