Observation of the exclusive reaction e(+)e(-)->phi eta at root s=10.58 GeV

We report the observation of e(+)e(-)->phi eta near root s=10.58 GeV with 6.5 sigma significance in the K+K-gamma gamma final state in a data sample of 224 fb(-1) collected by the BABAR experiment at the PEP-II e(+)e(-) storage rings. We measure the restricted radiation-corrected cross section to be sigma(e(+)e(-)->phi eta)=2.1 +/- 0.4(stat)+/- 0.1(syst) fb within the range vertical bar cos theta(*)vertical bar < 0.8, where theta(*) is the center-of-mass polar angle of the phi meson. The phi meson is required to be in the invariant mass range of 1.008 < m(phi)< 1.035 GeV/c(2). The radiation-corrected cross section in the full cos theta(*) range is extrapolated to be 2.9 +/- 0.5(stat)+/- 0.1(syst) fb

Observation of a new D-s meson decaying to DK at a mass of 2.86 GeV/c(2) RID C-2728-2008 RID C-5223-2009 RID C-5719-2008 RID D-1055-2009 RID A-2675-2009

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 (DK+)-K-0 and (D+KS0). In the same mass distributions, we also observe a broad structure with mass (2688 +/- 4(stat)+/- 3(syst)) MeV/c(2) and width (112 +/- 7(stat)+/- 36(syst)) MeV/c(2). To obtain this result, we use 240 fb(-1) of data recorded by the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV
