The authors investigate here superconducting UTe${}_{2}$ across a broad set of chiral and nonchiral order parameters and identify a clear experimental discriminator. A robust QPI peak, observed only in the superconducting state, emerges as the key fingerprint. Its dispersion and stability uniquely single out a B${}_{3u}$ pairing, which among the nonchiral pairing channels also appears to be the only one that exhibits a peak at zero energy in the DOS, consistent with the experimental observations.
