Search for Invisible Decay of the
The Belle Collaboration, O. Tajima, H. Hayashii +4
We report results of a search for the invisible decay of the Upsilon(1S) via the Upsilon(3S)->pi+pi-Upsilon(1S) transition using a data sample of 2.9 fb^{-1} at the Upsilon(3S) res…
Evidence for B-> eta' pi and improved measurements for B-> eta' K
The Belle Collaboration, J. Schuemann
We report evidence for exclusive two-body charmless hadronic B meson decays B-> eta' pi, and improved measurements of B-> eta' K. The results are obtained from a data sample of 386…
Improved Evidence for Direct CP Violation in B0 --> pi+ pi- Decays and Model-Independent Constraints on phi_2
Belle Collaboration, K. Abe
We present a new measurement of the time-dependent CP-violating parameters in B0 --> pi+ pi- decays with 275 x 10^6 BB-bar pairs collected with the Belle detector at the KEKB asymm…
Observation of a narrow charmonium-like state in exclusive B+ -> K+ pi+pi- J/psi decays
The Belle Collaboration, S. -K. Choi, S. L. Olsen
We report the observation of a narrow charmonium-like state produced in the exclusive decay process B+ -> K+ pi+pi- J/psi. This state, which decays into pi+pi- J/psi, has a mass of…
Observation of
A. Ishikawa
We report the first observation of the flavor-changing neutral current decay and an improved measurement of the decay , where $\ell…
Measurement of the CP Asymmetry in B -> X_s gamma
S. Nishida
Direct CP violation in the b->sgamma process is a sensitive probe of physics beyond the Standard Model. We report a measurement of the CP asymmetry in B -> X_s gamma, where the had…
