We report measurements of charmless hadronic B0 decays into the π+π-K+π- final state. The analysis uses a sample of 657×106 BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider at the resonance. The decay B0→ρ0K+π- is obs ...

We report a measurement of the exclusive e+e-→Λc+Λc- cross section as a function of center-of-mass energy near the Λc+Λc- threshold. A clear peak with a significance of 8.2σ is observed in the Λc+Λc- invariant mass distribution just above threshold. With a ...
