Measurement of the branching ratio of B ¯ →d (∗)τ- ν ¯ τ relative to B ¯ →d (∗) - ν ¯ decays with hadronic tagging at Belle

M. Huschle, +221 more
- 26 Oct 2015 - 
TL;DR: In this paper, the branching fraction ratio R(D)(()*()) of (B) over bar → D-(*())tau(-)(nu)over bar (tau) relative to (B), where l = e or mu, was measured using the full Belle data sample.
Journal ArticleDOI

Study of e + e - →π + π - J/ψ and Observation of a Charged Charmoniumlike State at Belle

Z. Q. Liu, +191 more
TL;DR: In a study of Y(4260) → π+ π- J/φ decays, a structure is observed in the M(π(±)J/ψ) mass spectrum with 5.2σ significance that can be interpreted as a new charged charmoniumlike state.
Journal Article

S. U. Kataoka, +159 more
Journal Article

Belle II technical design report

T. Abe, +409 more
TL;DR: In this article, an upgrade of the Belle detector at the KEKB electron-positron collider has been proposed, with an ultimate goal of 8E35 /cm^2 /s luminosity.
Journal ArticleDOI

Measurement of the τ Lepton Polarization and R (D * ) in the Decay B ̄ →D * τ - ν ̄ τ

S. Hirose, +193 more
TL;DR: The first measurement of the tau lepton polarization P-tau(D*) in the decay (B) over bar -> D* tau(-) (v) over b (tau) as well as a new measurement of the ratio of the branching fractions was reported in this paper.
