Description
Jet transverse single spin asymmetries, $A_N$, are only sensitive to the
initial state effects as final state effects are not present. They are
therefore an excellent tool to single out the quark-gluon and tri-gluon
correlation functions that are the higher-twist equivalents to the
transverse momentum moments of the Sivers functions for quarks and
gluons. sPHENIX has taken transversely polarized proton-proton collision
data at $\sqrt{s} = 200 \, GeV$ using a large acceptance full electromagnetic
and hadronic calorimetry to reconstruct jets. The status of the jet $A_N$
measurements will be presented.
