SUMMARY
The discussion centers on the constancy of the CKM matrix across various experimental energies. It is established that the CKM matrix provides ratios between weak decay rates, such as n → peν and Λ → peν, without an energy range dependency. According to the Standard Model, these parameters do exhibit energy dependence, as referenced in section 4.7 of the paper available at http://arxiv.org/abs/hep-ph/9912358. However, the potential running of these parameters may be too subtle to detect, as indicated by the lack of mention in the 2011 Particle Data Group review at http://pdg.lbl.gov/2011/reviews/rpp2011-rev-ckm-matrix.pdf.
