QCD evolution of the gluon Sivers function in heavy flavor dijet production at the Electron-Ion Collider

Heavy Flavor Production at the electron-proton collider HERA

An overview over the recent heavy flavor results of the H1 and ZEUS collaborations is presented. Various techniques to tag the heavy quark, which allow to explore different phase space regions, are employed. Predictions of pertubative QCD are compared to the charm and beauty production data. Charm and beauty fractions of the proton structure function F2 are extracted.

The Gluon Sivers Distribution in D Production at Rhic

The single transverse spin asymmetry in D meson production at RHIC can provide a clean measure of the gluon Sivers distribution function. At intermediate rapidity, D production is largely dominated by the elementary gg → cc̄ channel, where there cannot be any transverse spin transfer. Therefore, any transverse single spin asymmetry observed for D’s produced in pp interactions can only originate ...

QCD Factorization for heavy quarkonium production at collider energies

In this talk, I briefly review several models of the heavy quarkonium production at collider energies, and discuss the status of QCD factorization for these production models.
