Measurements of direct CP asymmetries in B → Xsγ decays using sum of exclusive decays

We measure the direct CP violation asymmetry, ACP, in B→Xsγ and the isospin difference of the asymmetry, ΔACP, using 429 fb−1 of data collected at Υ(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy e+e− storage rings operating at the SLAC National Accelerator Laboratory. B meson...
