Description

We explore the quark and the gluon sivers function which appear in the factorization theorem of dijet production in semi-inclusive deep inelastic scattering. We revise the unpolarized TMD case and state the possibility of re-defining the resummation method, altering the treatment of the corresponding evolution kernels. Studying the two resummation schemes we find strong dependence on gluon TMD distributions and big values of the Sivers asymmetry. For a given Sivers function model, we also present the impact of its uncertainty in the sivers weighted cross-section of the process.
