Search for invisible decays of the (1S)
We search for invisible decays of the Υ(1S) meson using a sample of 91.4×10[superscript 6] Υ(3S) mesons collected at the BABAR/PEP-II B factory. We select events containing the decay Υ(3S)→π[superscript +]π[superscript -]Υ(1S) and search for evidence of an undetectable Υ(1S) decay recoiling against...

| description | We search for invisible decays of the Υ(1S) meson using a sample of 91.4×10[superscript 6] Υ(3S) mesons collected at the BABAR/PEP-II B factory. We select events containing the decay Υ(3S)→π[superscript +]π[superscript -]Υ(1S) and search for evidence of an undetectable Υ(1S) decay recoiling against the dipion system. We set an upper limit on the branching fraction B(Υ(1S)→invisible)<3.0×10[superscript -4] at the 90% confidence level. |
