Untagged $B \to X_{(s+d)}$ gamma CP asymmetry as a probe for new physics
The direct CP asymmetry in the untagged inclusive channel B -> X_(s+d) gamma provides a strict test of the standard model. It has been shown beyond the partonic level that this asymmetry is negligibly small thanks to U-spin relations and to the unitarity of the CKM matrix. In the present paper we...
