Description

Neutral mesons transverse single spin asymmetries, $A_N$, provide insights
into the spin-orbit correlations inside the nucleon via higher twist
correlation functions. As forward rapidities they are known to be very
large while at central rapidities vanishing asymmetries have been
measured. The sPHENIX experiment with electromagnetic calorimetry over a
rapidity range from -1.1 to 1.1 will allow to extend the central
rapidity measurements performed by PHENIX and therefore access a region
that has not been covered well, yet.
The latest results from the 2024 proton-proton collisions at $\sqrt{s}=200\,$GeV will be presented.
