The COMPASS collaboration has recently released results of the gluon
contribution to the Sivers effect measurement from high-pt hadron pairs
both for proton and deuteron targets. The analysis method is based on the
assumption that in the high Q2 range three processes contribute to the
cross section: Leading Process, QCD Compton and Photon Gluon Fusion. The
selection of high-pt hadron...

Within a generalized TMD parton model we use the latest highly precise mid-rapidity data on A_N for inclusive neutral pion production in polarized pp collisions by the PHENIX Collaboration to get a first estimate of the still poorly known gluon Sivers distribution.
To this end we adopt present information on the quark Sivers functions as extracted from SIDIS data.
These results, together...
