Numerical precision radiative corrections to the Dalitz plot of light and heavy quark unpolarized baryon semileptonic decays: The cases Ξ0 → Σ eν̄ and Λc → ν Article uri icon

abstract

  • We propose and discuss a numerical use for our previous precision results for the radiative corrections to unpolarized spin one-half baryon semileptonic decays, which is not compromised to fixing the form factors at prescribed values. We present various cross-checks and comparisons with other results available in the literature of such analytical radiative corrections. Our analysis, however, is general and applies to all charge assignments to the baryons allowed by heavy quarks. The procedure is exemplified with the processes Ξ0 → Σ eν̄ and Λc → Λe ν. © 2005 The American Physical Society.
