The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

In the past decade, exotic hadrons with charm and bottom flavors have been extensively
studied both in experiments and in theories. In this review, we provide topical discussions by …

We report the first measurement of the τ lepton polarization P τ (D*) in the decay B¯→ D* τ-
ν¯ τ as well as a new measurement of the ratio of the branching fractions R (D*)= B (B¯→ D …

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 …

With the full data sample of 772× 10 6 BB¯ pairs recorded by the Belle detector at the KEKB
electron-positron collider, the decay B¯→ D* τ-ν¯ τ is studied with the hadronic τ decays τ-→ …

We report a measurement of the ratio R (D*)= B (B¯ 0→ D*+ τ-ν¯ τ)/B (B¯ 0→ D*+ ℓ-ν¯ ℓ),
where ℓ denotes an electron or a muon. The results are based on a data sample containing …

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 …

The experimental results on the ratios of branching fractions R (D)= B (B¯→ D τ-ν¯ τ)/B
(B¯→ D ℓ-ν¯ ℓ) and R (D*)= B (B¯→ D* τ-ν¯ τ)/B (B¯→ D* ℓ-ν¯ ℓ), where ℓ denotes an …

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 cross section for e+ e-→ π+ π-J/ψ between 3.8 and 5.5 GeV is measured with a 967 fb-1
data sample collected by the Belle detector at or near the Υ (n S)(n= 1, 2,…, 5) resonances …
