… In these synchrotron radiation calculations, we protect against beam tails out to 10σ x and
30σ y . The beam–beam simulations indicate no long tails in the interaction region. Mask-A …

… In retrospect, the first piRNAs found in Drosophila were those derived from the Suppressor
of Stellate locus on the Y chromosome (127). These piRNAs were suggested to target Stellate…

We report the observation of a narrow charmoniumlike state produced in the exclusive decay
process B ± → K ± π + π - J / ψ . This state, which decays into π + π - J / ψ , has a mass of …

We present a measurement of the standard model CP violation parameter sin 2 φ 1 based
on a 29.1 fb− 1 data sample collected at the ϒ (4 S) resonance with the Belle detector at the …

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) …

The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S)
events in its decade of operation. Super-KEKB, an upgrade of KEKB is under construction, …

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 BB pairs …

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

The cross section for e + e - → π + π - J / ψ between 3.8 and 5.5 GeV / c 2 is measured using
a 548 fb - 1 data sample collected on or near the Υ ( 4 S ) resonance with the Belle detector …
