Del Amo Sanchez P, Lees J, Poireau V, Prencipe E, Tisserand V, Garra Tico J, et al.
Phys Rev Lett . 2011 Aug; 107(4):041804. PMID: 21866995
We report the observation of the decay B- → D(s)((*)+) K- ℓ- ν(ℓ) based on 342  fb(-1) of data collected at the Υ(4S) resonance with the BABAR detector at the...

Del Amo Sanchez P, Lees J, Poireau V, Prencipe E, Tisserand V, Garra Tico J, et al.
Phys Rev Lett . 2011 Jul; 107(2):021804. PMID: 21797597
We search for single-photon decays of the Υ(1S) resonance, Υ → γ + invisible, where the invisible state is either a particle of definite mass, such as a light Higgs...

Phys Rev Lett . 2011 Jan; 105(17):172001. PMID: 21231035
We present a search for f(J)(2220) production in radiative J/ψ→γf(J)(2220) decays using 460  fb⁻¹ of data collected with the BABAR detector at the SLAC PEP-II e(+)e⁻ collider. The f(J)(2220) is...

Phys Rev Lett . 2010 Sep; 105(8):081803. PMID: 20868092
We report a direct measurement of D0-D0 mixing parameters through a time-dependent amplitude analysis of the Dalitz plots of D(0) → K(S)(0) π+ π- and, for the first time, D0...

Aubert B, Karyotakis Y, Lees J, Poireau V, Prencipe E, Prudent X, et al.
Phys Rev Lett . 2010 Sep; 105(5):051602. PMID: 20867905
Using 467  fb(-1) of e+e- annihilation data collected with the BABAR detector, we measure (B(τ- → μ- ν(μ) ν(τ)))/(B(τ- → e- ν(e) ν(τ))) =(0.9796±0.0016±0.0036), (B(τ- → π- ν(τ)))/(B(τ- → e-...

The ratio R(τμ)(Υ(1S))=Γ(Υ(1S)→τ+ τ-)/Γ(Υ(1S)→μ+ μ-) is measured using a sample of (121.8±1.2)×10(6)Υ(3S) events recorded by the BABAR detector. This measurement is intended as a test of lepton universality and as...

Phys Rev Lett . 2010 May; 104(15):151802. PMID: 20481982
Charged-lepton flavor-violating processes are unobservable in the standard model, but they are predicted to be enhanced in several extensions to the standard model, including supersymmetry and models with leptoquarks or...
