Study of $χ_{b 1, 2} (2 P) \to ω Υ (1 S)$ transitions in $Υ (3 S) \to γ χ_{b 1, 2} (2 P)$ decays at BaBar

The BABAR Collaboration

Results are presented on $χ_{b 1, 2} (2 P) \to ω Υ (1 S)$ transitions from $e^{+} e^{-} \to Υ (3 S) \to γ χ_{b 1, 2} (2 P)$ decays. The data were collected with the BaBar detector at the PEP-II asymm…

A search for baryogenesis and dark matter in $B^{+} \to Λ_{c}^{+} + invisible$ decays

BABAR Collaboration

A mechanism of baryogenesis and dark matter production via $B$ -meson oscillations and decays has recently been proposed to explain the observed dark matter abundance and matter-ant…

Measurement of additional radiation in the initial-state-radiation processes $e^{+} e^{-} \to μ^{+} μ^{-} γ$ and $e^{+} e^{-} \to π^{+} π^{-} γ$ at BABAR

BABAR Collaboration

A dedicated measurement of additional radiation in $e^{+} e^{-} \to μ^{+} μ^{-} γ$ and $e^{+} e^{-} \to π^{+} π^{-} γ$ initial-state-radiation events is presented using the full BABAR data sample. For the f…

Measurement of the $γ^{⋆} γ^{⋆} \to η^{'}$ transition form factor

The BaBar collaboration

We study the process $e^{+} e^{-} \to e^{+} e^{-} η^{'}$ in the double-tag mode and measure for the first time the $γ^{⋆} γ^{⋆} \to η^{'}$ transition form factor $F_{η^{'}} (Q_{1}^{2}, Q_{2}^{2})$ in th…

Measurement of the spectral function for the $τ^{-} \to K^{-} K_{S} ν_{τ}$ decay

The BaBar Collaboration

The decay $τ^{-} \to K^{-} K_{S} ν_{τ}$ has been studied using $430 \times 1 0^{6}$ $e^{+} e^{-} \to τ^{+} τ^{-}$ events produced at a center-of-mass energy around 10.6 GeV at the PEP-II collider and stu…

Study of the process $e^{+} e^{-} \to π^{+} π^{-} η$ using initial state radiation

The BABAR Collaboration

We study the process $e^{+} e^{-} \to π^{+} π^{-} η γ$ , where the photon is radiated from the initial state. About 8000 fully reconstructed events of this process are selected from the BaBar d…

Search for the decay B^0 --> gamma-gamma

the BABAR Collaboration, B. Aubert

We present a limit on the branching fraction for the decay $B^{0} \to γ γ$ using data collected at the $Υ (4 S)$ resonance with the BABAR detector at the PEP-II asymmetric--energy $e^+e…

Determination of the Michel Parameters rho, xi, and delta in tau-Lepton Decays with tau --> rho nu Tags

ARGUS Collaboration

Using the ARGUS detector at the $e^{+} e^{-}$ storage ring DORIS II, we have measured the Michel parameters $ρ$ , $ξ$ , and $ξ δ$ for $τ^{\pm} \to l^{\pm} ν ν ˉ$ decays in $τ$ -pair events…
