Branching fraction measurements of B → η c K decays
We study the decays B+ -> etac K+ and B0 -> etac K0, where the etac is reconstructed in the Ks K+ pi- and K+ K- pi0 decay modes. Results are based on a sample of 86 million BBbar pairs collected with the BaBar detector at the SLAC e+e- B Factory. We measure the branching fractions BR(B+ ->...

| description | We study the decays B+ -> etac K+ and B0 -> etac K0, where the etac is reconstructed in the Ks K+ pi- and K+ K- pi0 decay modes. Results are based on a sample of 86 million BBbar pairs collected with the BaBar detector at the SLAC e+e- B Factory. We measure the branching fractions BR(B+ -> etac K+) = (1.34 +/- 0.09 +/- 0.13 +/- 0.41) x 10^{-3} and BR(B0 -> etac K0) = (1.18 +/- 0.16 +/- 0.13 +/- 0.37) x 10^{-3}, where the first error is statistical, the second is systematic, and the third reflects the etac branching fraction uncertainty. In addition, we search for B -> etac K events with etac -> 2(K+K-) and etac -> phi phi and determine the etac decay branching fraction ratios BR(etac -> 2(K+K-))/BR(etac -> K Kbar pi) = (2.3 +/- 0.7 +/- 0.6) x 10^{-2} and BR(etac -> phi phi)/BR(etac -> K Kbar pi) = (5.5 +/- 1.4 +/- 0.5) x 10^{-2}. |

Results are based on a sample of 86 million BBbar pairs collected with the BaBar detector at the SLAC e+e- B Factory. We measure the branching fractions BR(B+ -> etac K+) = (1.34 +/- 0.09 +/- 0.13 +/- 0.41) x 10^{-3} and BR(B0 -> etac K0) = (1.18 +/- 0.16 +/- 0.13 +/- 0.37) x 10^{-3}, where the first error is statistical, the second is systematic, and the third reflects the etac branching fraction uncertainty. In addition, we search for B -> etac K events with etac -> 2(K+K-) and etac -> phi phi and determine the etac decay branching fraction ratios BR(etac -> 2(K+K-))/BR(etac -> K Kbar pi) = (2.3 +/- 0.7 +/- 0.6) x 10^{-2} and BR(etac -> phi phi)/BR(etac -> K Kbar pi) = (5.5 +/- 1.4 +/- 0.5) x 10^{-2}.</abstract><pub>American Physical Society</pub><doi>10.1103/PhysRevD.70.011101</doi><orcidid>https://orcid.org/0000-0003-4774-2194</orcidid><orcidid>https://orcid.org/0000-0002-5821-9617</orcidid><orcidid>https://orcid.org/0000-0003-4073-6541</orcidid><orcidid>https://orcid.org/0000-0003-4887-2150</orcidid><orcidid>https://orcid.org/0000-0003-3332-2615</orcidid><orcidid>https://orcid.org/0000-0003-2655-7643</orcidid><orcidid>https://orcid.org/0000-0003-4249-6641</orcidid><orcidid>https://orcid.org/0000-0002-3110-6022</orcidid><orcidid>https://orcid.org/0000-0002-1278-109X</orcidid><orcidid>https://orcid.org/0000-0002-8859-5453</orcidid><orcidid>https://orcid.org/0000-0002-9495-9145</orcidid></addata></record> |
