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…

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…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} π^{0} π^{0}$ cross section using initial-state radiation at BaBar

The BaBar Collaboration

The process $e^{+} e^{-} \to π^{+} π^{-} 2 π^{0} γ$ is investigated by means of the initial-state radiation technique, where a photon is emitted from the incoming electron or positron. Using $454…
