Leading log PDFs suffice for high-energy predictions in muon colliders, as indicated by a comparison of unresummed next-to-leading log (NLL) and leading log (LL) PDFs. Discrepancies between the two approximations remain below 10% at 5 TeV and around 40% at 50 TeV, supporting the conclusion that the leading log approximation is robust for most applications. These results imply that for precision predictions at higher levels, further evaluation might be necessary, as leading log PDFs adequately capture the essential dynamics.
Comparisons of unresummed NLL and LL PDFs demonstrate that leading log PDFs are sufficient for many high-energy predictions, providing robust results in muon collider scenarios.
The analysis shows that discrepancies between NLL and LL approximations for PDFs are small, suggesting strong confidence in leading log approximations for practical predictions.
