The effect of new update of Beta Factory SIA data on Kaon Fragmentation Function

• Hamed Abdolmaleki (School of Physics, IPM)

For the first time we investigate the role of new update of Belle single-inclusive annihilation data on Kaon Fragmentation Function. This analysis was implemented as an open-source framework (xFitter). This study incorporates a comprehensive and up-to-date set of Kaon production data from (SIA) processes, together with the most recent measurements of inclusive cross-sections of single Kaon by the BELLE collaboration. The determination of Kaon FFs along with their theoretical uncertainties is performed in the zero-mass variable-flavor number scheme (ZM-VFNS). The resulting NLO and NNLO Kaon FFs provide valuable insights for applications in present and future high-energy analysis of Kaon final state processes.
