We present a measurement of angular observables and a test of lepton flavor universality in
the B→ K* ℓ+ ℓ-decay, where ℓ is either e or μ. The analysis is performed on a data sample …

We report a measurement of the branching fraction ratios R (D (*)) of B¯→ D (*) τ-ν¯ τ
relative to B¯→ D (*) ℓ-ν¯ ℓ (where ℓ= e or μ) using the full Belle data sample of 772× 10 6 …

A bstract We present measurements of the branching fractions for the decays B→ Kμ+ μ−
and B→ Ke+ e−, and their ratio (RK), using a data sample of 711 fb− 1 that contains 772× 10 …

The inspiration for this book came from François le Diberder. During his term as
spokesperson for B 八 B 八 R he laid down a vision for the two B Factory detector …

We present a measurement of RK*, the branching fraction ratio B (B→ K* μ+ μ-)/B (B→ K* e+
e-), for both charged and neutral B mesons. The ratio for the charged case RK*+ is the first …

A search for the flavor-changing neutral-current decay B+→ K+ ν ν¯ is performed at the Belle
II experiment at the SuperKEKB asymmetric energy electron-positron collider. The data …

There exist many experimental indications that final-state interactions (FSIs) may play a
prominent role not only in charmful B decays but also in charmless B ones. We examine the …

We present the results of a search for the rare decays B→ h ν ν¯, where h stands for K+, KS
0, K*+, K* 0, π+, π 0, ρ+ and ρ 0. The results are obtained with 772× 10 6 BB¯ pairs collected …

We report the results of a study of the exclusive semileptonic decays B-→ π 0 ℓ-ν¯ ℓ, B¯ 0→
π+ ℓ-ν¯ ℓ, B-→ ρ 0 ℓ-ν¯ ℓ, B¯ 0→ ρ+ ℓ-ν¯ ℓ and B-→ ω ℓ-ν¯ ℓ, where ℓ represents an …

We report evidence for direct CP violation in the decay B 0→ K+ π-with 253 fb-1 of data
collected with the Belle detector at the KEKB e+ e-collider. Using 275× 10 6 BB¯ pairs we …
