Precision Measurement of the B→X[subscript s]γ Photon Energy Spectrum, Branching Fraction, and Direct CP Asymmetry A[subscript CP](B→X[subscript s+d]γ)
The photon spectrum in the inclusive electromagnetic radiative decays of the B meson, B→X[subscript s]γ plus B→X[subscript d]γ, is studied using a data sample of (382.8±4.2)×10[superscript 6]Υ(4S)→BB̅ decays collected by the BABAR experiment at SLAC. The spectrum is used to extract the branching fra...
