Our study employs a two-parameter representation of the DA at $\\zeta=2$ GeV, designed to capture the expected broadening and asymmetry of the distribution, as well as the soft endpoint behavior predicted by quantum chromodynamics (QCD). Our leading-order analysis of the latest experimental measurements of $\\mathcal{R}_K$ reveals that the extracted DA exhibits a somewhat significant s","authors_text":"Kh\\'epani Raya, Lei Chang, M.
