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 ) …

This article reports world averages of measurements of b-hadron, c-hadron, and $$\tau $$ τ
-lepton properties obtained by the Heavy Flavor Averaging Group using results available …

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 B …

We report the observation of two narrow structures in the mass spectra of the π ± Υ ( n S ) ( n
= 1 , 2, 3) and π ± h b ( m P ) ( m = 1 , 2) pairs that are produced in association with a single …

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 → …

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 …

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 …

One of the key assumptions of the standard model of particle physics is that the interactions
of the charged leptons, namely electrons, muons and taus, differ only because of their …
