Search for B0 -> rho0rho0 and Non-Resonant B0 -> 4pi Decays
BELLE Collaboration, K. Abe
We search for the decay B0 -> rho0rho0 and other possible charmless modes with a pi+pi-pi+pi- final state, including B0 -> rho0f0(980), B0 -> f0(980)f0(980), B0 -> f0(980)pipi, B0…
Search for new charmonium states in the processes e+ e- --> J/psi D(*) D(*) at sqrt{s} ~ 10.6 GeV
Belle Collaboration, K. Abe
We present a study of the X(3940) state in the process e+e- -> J/psi D* Dbar. The X(3940) mass and width are measured to be (3942 +7 -6 +- 6)MeV/c^2 and Gamma=(37 + 26 - 15 +- 8 Me…
Measurement of phi_3 with Dalitz Plot Analysis of B->D(*)K Decay at Belle
Belle Collaboration, K. Abe
We present a measurement of the unitarity triangle angle phi_3 using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B->D(*)K process. Using a 253 fb…
Improved Measurements of Color-Suppressed Decays B0bar -> D0 pi0, D0 eta and D0 omega
Belle Collaboration, K. Abe
We present preliminary improved measurements of the branching fractions of the color-suppressed decays B0bar -> D0 h0, where h0 represents the three light neutral mesons pi0, eta a…
