A Search for the rare decay B0 --> tau+tau- at BABAR

The BABAR Collaboration, B. Aubert

We present the results of a search for the decay B0 --> tau+tau- in a data sample of (232 +- 3) x 10^6 Upsilon(4S) --> BBbar decays using the BABAR detector. Certain extensions of…

Measurement of Double Charmonium Production in $e^{+} e^{-}$ Annihilations at $s = 10.6$ GeV

The BABAR Collaboration, B. Aubert

We study $e^{+} e^{-} \to J / ψ c c ˉ$ by measuring the invariant mass distribution recoiling against fully reconstructed $J / ψ$ decays, using 124 fb $^{- 1}$ of data collected with a cente…

Observation of B0 Meson decays to a1(1260) pi

B. Aubert, BaBar Collaboration

We present preliminary measurements of the B meson decay B0 -> a1(1260)+ pi-, with a1(1260)+ --> pi+ pi+ pi-. The data were recorded with the BABAR detector at PEP II and correspon…

Study of the X(3872) and Y(4260) in B0-->J/psi pi+ pi- K0 and B-->J/psi pi+ pi- K- decays

B. Aubert, BABAR Collaboration

We present results of a search for the X(3872) in B0-->X(3872)KS0,X(3872)-->J/psi pi+ pi-, improved measurements of B-->X(3872)K-, and a study of the J/psi pi+ pi- mass region abov…

Study of the tau- --> 3h-2h+nu Decay

B. Aubert

The branching fraction of the tau- --> 3h- 2h+ nu decay (h= pi, kaon) is measured with the BaBar detector to be (8.56 +/- 0.05 +/- 0.42)E-04 where the first error is statistical an…

Observation of a Broad Structure in the $π^{+} π^{-} J / ψ$ Mass Spectrum around 4.26 GeV/ $c^{2}$

The BABAR Collaboration, B. Aubert

We study initial-state radiation events, $e^{+} e^{-} \to γ_{I S R} π^{+} π^{-} J / ψ$ , with data collected with the BaBar detector. We observe an accumulation of events near 4.26 GeV/ $c^{2}$ in the…
