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…

Search for a Dark Leptophilic Scalar at BABAR

The BABAR Collaboration

Many scenarios of physics beyond the Standard Model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constrai…

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…
