This research aims to explore the rare semileptonic decays of Xi_b baryons and their characteristics through theoretical calculations.
Decay processes analyzed include Xi_b^- to Xi^- l^+ l^- and Xi_b^0 to Lambda l^+ l^- with calculations based on the relativistic quark model.
Form factors are computed using a quasipotential approach informed by quantum chromodynamics.
Decay widths, asymmetries, and polarization characteristics are derived using helicity formalism and account for long-range contributions.
Predictions show detailed decay widths for Xi_b baryons across three lepton generations.
Asymmetries and polarization characteristics of the decays are quantitatively evaluated, providing a nuanced understanding of baryon interactions.
Effects of charmonium vector resonances on Wilson coefficients are assessed, contributing to predictions of decay behavior.
