Aubert B, Barate R, Bona M, Boutigny D, Couderc F, Karyotakis Y, et al.
Phys Rev Lett . 2007 Aug; 98(21):212001. PMID: 17677767
We present a measurement of the cross section of the process e(+)e(-)-->pi(+)pi(-)psi(2S) from threshold up to 8 GeV center-of-mass energy using events containing initial-state radiation, produced at the SLAC PEP-II...

Aubert B, Barate R, Boutigny D, Couderc F, Karyotakis Y, Lees J, et al.
Phys Rev Lett . 2007 Aug; 98(21):211804. PMID: 17677766
We present a measurement of the partial branching fractions and mass spectra of the exclusive radiative penguin processes B-->Kpipigamma in the range m(Kpipi)<1.8 GeV/c(2). We reconstruct four final states: K(+)pi(-)pi(+)gamma,...

Phys Rev Lett . 2007 May; 98(14):141801. PMID: 17501265
Using 230.2 fb-1 of e+e- annihilation data collected with the BABAR detector at and near the peak of the Upsilon(4S) resonance, 489+/-55 events containing the pure leptonic decay Ds+-->micro;+numicro have...

Aubert B, Barate R, Bona M, Boutigny D, Couderc F, Karyotakis Y, et al.
Phys Rev Lett . 2007 Mar; 98(8):081801. PMID: 17359085
We report the observation of decays B{0}-->D{s}{(*)+}pi- and B{0}-->D{s}{(*)-}K+ in a sample of 230 x 10(6) Upsilon(4S)-->BB[over] events recorded with the BABAR detector at the SLAC PEP-II asymmetric-energy e+ e-...

Aubert B, Barate R, Bona M, Boutigny D, Couderc F, Karyotakis Y, et al.
Phys Rev Lett . 2007 Mar; 98(5):051803. PMID: 17358845
We present a measurement of the branching fraction and time-dependent CP asymmetry of B(0)-->rho0K0. The results are obtained from a data sample of 227x10(6) Upsilon(4S)-->BB decays collected with the BABAR...

Phys Rev Lett . 2007 Mar; 98(5):051802. PMID: 17358844
We present an observation of B-->eta'K*. The data sample corresponds to 232x10(6) BB[over ] pairs collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the Stanford Linear...

Phys Rev Lett . 2007 Mar; 98(1):012001. PMID: 17358468
A search for charmed baryons decaying to D(0)p reveals two states: the Lambdac(2880)+ baryon and a previously unobserved state at a mass of [2939.8+/-1.3(stat)+/-1.0(syst)] MeV/c2 and with an intrinsic width...

Phys Rev Lett . 2006 Dec; 97(22):222001. PMID: 17155795
We observe a new D_{s} meson with mass (2856.6+/-1.5_{stat}+/-5.0_{syst}) MeV/c;{2} and width (48+/-7_{stat}+/-10_{syst}) MeV/c;{2} decaying into D0K+ and D;{+}K_{S};{0}. In the same mass distributions, we also observe a broad structure...

Phys Rev Lett . 2006 Dec; 97(22):221803. PMID: 17155794
We analyze 230.4 fb;{-1} of data collected with the BABAR detector at the PEP-II e;{+}e;{-} collider at SLAC to search for evidence of D0-D[over ];{0} mixing using regions of phase...
