Description
We present the preliminary results for the Collins and Sivers amplitudes of the transverse target spin asymmetries (TSAs) in production of neutral kaons ($K^0$) in semi-inclusive deep inelastic scattering. The results were obtained using the data accumulated at COMPASS in 2022 on a transversely polarized $^6$LiD target. The amplitudes were extracted using an unbinned maximum likelihood approach and the kinematic dependences on $x$, $z$ and $p_{T}$ are presented. As a complement to previously measured Collins and Sivers amplitudes for the production of single charged hadrons , these results are a step toward improving our understanding of nucleon structure.
