Ajay Kumar Rai, Manakkumar Parmar

Theoretical mass variations from wavefunction models cause pronounced non-linear sensitivity in predicted branching fractions of heavy-light meson decays.

Claims

C1strongest claim

the theoretical mass variation between wavefunction models induces a pronounced, non-linear sensitivity in the branching fractions, establishing the accurate Gaussian mass as a crucial baseline

C2weakest assumption

The factorization framework remains valid enough for quantitative predictions once the meson mass is fixed, even though the abstract itself notes that final-state interactions limit it in the charm sector.

C3one line summary

Theoretical mass variations between Gaussian and hydrogenic wavefunctions induce pronounced non-linear sensitivity in two-body non-leptonic branching fractions of D, Ds, B, and Bs mesons under factorization, with Gaussian masses aligning better for bottom decays.
