Study of e+ e- → π+ π- J/ψ and observation of a charged charmoniumlike state at Belle.
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.
Search for heavy neutrinos at Belle
We report on a search for heavy neutrinos in $B$-meson decays. The results are obtained using a data sample that contains $772\ifmmode\times\else\texttimes\fi{}{10}^{6}B\overline{B}$ pairs collected
Measurement of the CKM matrix element |Vcb| from B0→D*−ℓ+νℓ at Belle
We present a new measurement of the CKM matrix element $|V_{cb}|$ from $B^{0} \to D^{*-} \ell^+ \nu_\ell$ decays, reconstructed with the full Belle data set of $711 \, \rm fb^{-1}$ integrated
Measurement of R(D) and R(D^{*}) with a Semileptonic Tagging Method.
This work constitutes the most precise measurements of R(D) and R (D^{*}) performed to date as well as the first result for R( D) based on a semileptonic tagging method.
Precise measurement of the CP violation parameter sin2φ1 in B0→(cc¯)K0 decays.
We present a precise measurement of the CP violation parameter sin2φ1 and the direct CP violation parameter A(f) using the final data sample of 772×10(6) BB[over ¯] pairs collected at the Υ(4S)
Measurement of the branching fraction B(Λc+ → pK-π+).
We present the first model-independent measurement of the absolute branching fraction of the Λ(c)(+) → pK(-)π(+) decay using a data sample of 978 fb(-1) collected with the Belle detector at the KEKB
Search for Time-Dependent CPT Violation in Hadronic and Semileptonic B Decays
We report a new sensitive search for C P T violation, which includes improved measurements of the C P T-violating parameter z and the total decay-width difference normalized to the averaged width
One-step solvothermal synthesis of Fe3O4@C core-shell nanoparticles with tunable sizes.
It is demonstrated that the FCNPs can effectively remove more than 90 wt% of Cr(VI) from aqueous solution and the role of glucose in regulating the grain size and morphology of the particles is discussed.
Origin of the Two-Dimensional Electron Gas at LaAlO 3 /SrTiO 3 Interfaces: The Role of Oxygen Vacancies and Electronic Reconstruction
The relative importance of atomic defects and electron transfer in explaining conductivity at the crystalline LaAlO3/SrTiO3 interface has been a topic of debate. Metallic interfaces with similar
