Observation of [ital B][sup 0] decay to two charmless mesons
We report results from a search for the decays [ital B][sup 0][r arrow][pi][sup +][pi][sup [minus]], [ital B][sup 0][r arrow][ital K][sup +][pi][sup [minus]], and [ital B][sup 0][r arrow][ital K][sup +][ital K[minus]]. We find 90% confidence level upper limits on the branching fractions, [ital B][su...

| description | We report results from a search for the decays [ital B][sup 0][r arrow][pi][sup +][pi][sup [minus]], [ital B][sup 0][r arrow][ital K][sup +][pi][sup [minus]], and [ital B][sup 0][r arrow][ital K][sup +][ital K[minus]]. We find 90% confidence level upper limits on the branching fractions, [ital B][sub [pi][pi]][lt]2.9[times]10[sup [minus]5], [ital B][sub [ital K][pi]][lt]2.6[times]10[sup [minus]5], and [ital B][sub [ital K][ital K]][lt]0.7[times]10[sup [minus]5]. While there is no statistically significant signal in the individual modes, the sum of [ital B][sub [pi][pi]] and [ital B][sub [ital K][pi]] exceeds zero with a significance of more than 4 standard deviations, indicating that we have observed charmless hadronic [ital B] decays. |

0][r arrow][pi][sup +][pi][sup [minus]], [ital B][sup 0][r arrow][ital K][sup +][pi][sup [minus]], and [ital B][sup 0][r arrow][ital K][sup +][ital K[minus]]. We find 90% confidence level upper limits on the branching fractions, [ital B][sub [pi][pi]][lt]2.9[times]10[sup [minus]5], [ital B][sub [ital K][pi]][lt]2.6[times]10[sup [minus]5], and [ital B][sub [ital K][ital K]][lt]0.7[times]10[sup [minus]5]. While there is no statistically significant signal in the individual modes, the sum of [ital B][sub [pi][pi]] and [ital B][sub [ital K][pi]] exceeds zero with a significance of more than 4 standard deviations, indicating that we have observed charmless hadronic [ital B] decays.</abstract><cop>United States</cop><doi>10.1103/PhysRevLett.71.3922</doi></addata></record> |
