Abstract:

We report a new measurement of transverse single-spin asymmetries for dijet production in collisions of polarized protons at $\sqrt{s}$ = 200 GeV. Possible correlations between the proton spin $\vec S$ and the transverse momenta of its partons, $\vec k_T$, perpendicular to each other and both transverse to the proton momentum direction $\vec P$, are probed at high $Q^2$ ($\sim$160 GeV$^2$). The associated Sivers observable $\kt$ is extracted using simple kinematics. Non-zero Sivers effects are observed for the first time in $\rm{pp}$ collisions, but only when the jets are sorted by their net charge, which enhances the $u$- or $d$-quark contributions to separate data samples. This also enables a determination of the individual partonic contributions to the observed asymmetries.
