Measurements of direct CP asymmetries in B→Xsγ decays using sum of exclusive decays
J. P. Lees, V. Poireau, V. Tisserand, E. Graugés et autres
We measure the direct $CP$ violation asymmetry, ${A}_{CP}$, in $B\ensuremath{\rightarrow}{X}_{s}\ensuremath{\gamma}$ and the isospin difference of the asymmetry, $\mathrm{\ensuremath{\Delta}}{A}_{CP}$, using $429\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected at $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance with the BABAR detector at the PEP-II asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ storage rings operating at the …
