Transverse $Λ$ polarization in $e^+e^-$ annihilations and in SIDIS processes at the EIC within TMD factorization
Year: 2023
Type: preprint
Abstract: We present a phenomenological study on the role of charm contribution and $SU(2)$ isospin symmetry in the extraction of the $Λ$ polarizing fragmentation functions from $e^+e^- \to Λ^\uparrow (\barΛ^\uparrow) \,h + X$ annihilation processes. We adopt the well-established transverse-momentum-dependent factorization formalism, within the Collins-Soper-Sterman evolution scheme at next-to-leading logarithm accuracy, carefully exploiting the role of the nonperturbative component of the polarizing fragmentation function. We then discuss the impact of these results on the predictions for transverse $Λ$, $\barΛ$ polarization in semi-inclusive deep inelastic scattering processes at typical energies of the future Electron-Ion Collider.
