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 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 ArticleDOI

Observation of two charged bottomoniumlike resonances in Υ(5S) decays.

A.E. Bondar, +157 more
TL;DR: The observation of two narrow structures in the mass spectra of the π(±)Υ(nS) and π (±)h(b)(mP) pairs that are produced in association with a single charged pion in Υ(5S) decays is reported.
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 ArticleDOI

Observation of the DsJ(2317) and DsJ(2457) in B Decays

P. Krokovny, +166 more
TL;DR: In this article, the first observation of the B-->D over barD(sJ)(2317) and B->D>D-s*gamma decays based on 123.8x10(6) B (B) was reported.
