Observation of a Narrow Charmoniumlike State in Exclusive B±→K±π+π-J/ψ Decays

Suyong Choi, +175 more
TL;DR: In this article, a narrow charmonium-like state produced in the exclusive decay process B+/--->K+/-pi(+)pi(-)J/psi has been observed, which has a mass of 3872.0+/-0.6(stat)+/- 0.5(syst) MeV.
Journal ArticleDOI

Observation of Large CP Violation in the Neutral B Meson System

Kazuo Abe, +250 more
TL;DR: The standard model CP violation parameter sin2 phi(1) is measured based on a data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider and it is concluded that the neutral B meson system is observed.
Journal Article

Observation of B̄0 → D(*)0 pp̄

Kazuo Abe, +202 more
TL;DR: The B meson decay modes B -->Dpp; and B-->D(*)pp; have been studied using 29.4 fb(-1) of data collected with the Belle detector at KEKB using the corresponding upper limits at 90% C.L. are presented.
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.
