Book Description
Abstract: We present a data analysis using 124.3 fb−1 of data from the BaBar detector. The analysis is a measurement of the branching fractions for the singly Cabibbo-suppressed decay mode BF([meson] [to] [pion] [pion]0) = (1.21 " 0.10 (stat.) " 0.08 (sys.) " 0.08 (pdg)) x 10−3 and for the doubly Cabibbo-suppressed decay mode BF([meson]+ [to] [kaon]+ [pion]0)= (2.11 " 0.43 (stat.) " 0.15 (sys.) " 0.16 (pdg)) x 10−4, where the first error is statistical, the second is systematic and the last is due to the D absolute branching fraction scale.

Book Description
This document presents results of the search for B + → etaXK+ in which etaX → etapi+pi - or etaX → K0S K+pi-, and etaX is a potentially exotic state with a resonant mass within (1.2-1.8) GeV. We use the BABAR data of 382.9 million BB pairs and report the first observation of B+ → eta(1295) K+ and B+ → eta(1475)K+, and set upper limits for the modes listed below. We also consider an alternative signal model in the etaX → K0S K+/-pi∓ mode with an extra resonance, to better describe the meson mass spectrum. We provide the central values where possible. Hermitian conjugation is implied throughout the document unless stated otherwise. BB+/- →h1295 K+/- xBh 1295→h pp=2.93+0.77+0.22 -0.73-0.21 ˙10-6, BB+/- →h1475 K+/- xBh 1475→ KK&d1;p =13.79+1.83+1.00-1.65-0.56 ˙10-6. The following upper limits assume 90% C.L: BB+/- →f11285 K+/-xB f11285 →hpp
