Study of the reaction e^{+}e^{-}->psi(2S)pi^{-}pi^{-} via initial state radiation at BaBar

The BABAR Collaboration

We study the process $e^{+} e^{-} \to ψ (2 S) π^{+} π^{-}$ with initial-state-radiation events produced at the PEP-II asymmetric-energy collider. The data were recorded with the \BaBar detect…

Exclusive Measurements of b -> s gamma Transition Rate and Photon Energy Spectrum

The BABAR Collaboration

We use 429 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at the $Υ (4 S)$ resonance with the BABAR detector to measure the radiative transition rate of $b \to s γ$ with a sum…
