Abstract

The production of vector mesons in deep inelastic scattering is an interesting yet scarcely explored channel to study the transverse spin structure of the nucleon and the spin-dependence of fragmentation. The COMPASS collaboration has performed the first measurement of the Collins and Sivers asymmetries for inclusively produced rho(0) mesons. The analysis is based on the data set collected in deep inelastic scattering in 2010 using a 160 GeV/c mu(+) beam impinging on a transversely polarized NH3 target. The rho(0) mesons are selected from oppositely charged hadron pairs, and the asymmetries are extracted as a function of the Bjorken-xvariable, the transverse momentum of the pair and the fraction of the energy z carried by the pair. Indications for positive Collins and Sivers asymmetries are observed.(c) 2023 The Author(s). Published by Elsevier B.V.

The rho(0) mesons are selected from oppositely charged hadron pairs, and the asymmetries are extracted as a function of the Bjorken-xvariable, the transverse momentum of the pair and the fraction of the energy z carried by the pair. Indications for positive Collins and Sivers asymmetries are observed.(c) 2023 The Author(s). Published by Elsevier B.V.
