Study of B Decays into the Final State Dπππ at BABAR
نویسنده
چکیده
Based on a data sample of an integrated luminosity of 57.4 fb at the Υ(4S) resonance taken with the BABAR detector using the SLAC PEP-II asymmetric-energy B-Factory, hadronic decays of B meson with the final states D and three pions are studied. The study is performed by fully reconstructing the exclusive decays of B → Da1(1260) and the non-resonant modes B → D ρπ and B → Dπππ. The current status of the study is presented and a dominant B → Da1(1260) decay is shown.

متن کاملStudies of B decays to Charmonium at BABAR
Using 22.7M BB events recorded by the BaBar detector, the inclusive branching ratios for the production of J/ψ , ψ(2S) and χc in B decays are presented. Combining the charmonium state with a K± , K, K∗± , K∗0 or π, B decays are reconstructed exclusively and their branching fractions are determined. A preliminary study is also presented for the B → ηcK decay mode.
متن کاملMeasurements of sin 2 β at B A B AR with charmonium and penguin decays
Measurements of sin 2β at BABAR with charmonium and penguin decays. Abstract This article summarises measurements of time-dependent CP asymmetries in decays of neutral B mesons to charmonium, open-charm and gluonic penguin-dominated charmless final states. Unless otherwise stated, these measurements are based on a sample of approximately 230 million Υ (4S)→ BB decays collected by the BABAR dete...
متن کاملEffects of Final-State Interactions in Hadronic B Decays
Although the importance of final-state interactions (FSIs) has long been recognized in hadronic charm decays, the general folklore for hadronic B decays is that FSIs are expected to play only a minor role there due to the large energy release in the energetic B decay. However, there are growing hints at some possible soft final-state rescattering effects in B decays. The measurement of the colo...
