The CP asymmetry is measured as a function of the photon energy threshold. For E-gamma* >= 2.1 GeV, where E-gamma* is the photon energy in the center-of-mass frame, we obtain A(CP) ((B) over bar -> Xs+d gamma) = (2.2 +/- 3.9 +/- 0.9)%, consistent with the standard model prediction.text::journal::journal article::research article
