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…

Resonances in $e^{+} e^{-}$ annihilation near 2.2 GeV

The BABAR Collaboration

Using the initial-state radiation method, the $e^{+} e^{-} \to K_{S} K_{L}$ cross section from 1.98 to 2.54 GeV is measured in a data sample of 469 fb $^{- 1}$ collected with the BABAR detect…

First evidence for $cos 2 β > 0$ and resolution of the CKM Unitarity Triangle ambiguity by a time-dependent Dalitz plot analysis of $B^{0} \to D^{(*)} h^{0}$ with $D \to K_{S}^{0} π^{+} π^{-}$ decays

The BaBar, Belle Collaborations, : +422

We present first evidence that the cosine of the CP-violating weak phase $2 β$ is positive, and hence exclude trigonometric multifold solutions of the CKM Unitarity Triangle using a…

Study of $Υ (1 S)$ Radiative Decays to $γ π^{+} π^{-}$ and $γ K^{+} K^{-}$

J. P. Lees

We study the $Υ (1 S)$ radiative decays to $γ π^{+} π^{-}$ and $γ K^{+} K^{-}$ using data recorded with the BaBar detector operating at the SLAC PEP-II asymmetric-energy $e^{+} e^{-}$ collider at…
