First Measurement of $R (X_{τ / ℓ})$ as an Inclusive Test of the $b \to c τ ν$ Anomaly

Belle II Collaboration, I. Adachi, K. Adamczyk +390

We measure the tau-to-light-lepton ratio of inclusive $B$ -meson branching fractions $R (X_{τ / ℓ}) \equiv B (B \to X τ ν) / B (B \to X ℓ ν)$ , where $ℓ$ indicate…
