B̄ → X s γ : Standard Model and Beyond †
نویسنده
چکیده
We present a concise review of the recent theoretical progress concerning the standard model calculation of the inclusive radiative B̄ → Xsγ decay. Particular attention is thereby devoted to the calculations of the next-to-next-to-leading order fixed-order O(αs) contributions, non-local O(αsΛ/mb) power corrections, and logarithmic-enhanced O(αs) cut-effects to the decay rate. The current status of various beyond the standard model calculations of the inclusive b → sγ mode is also summarized.

Untagged B̄ → X s + d γ CP asymmetry as a probe for new physics
The direct CP asymmetry in the untagged inclusive channel B̄ → Xs+d γ 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 investigate this relation beyond the SM; in particular, we analyse to which extent deviations from this pre...
متن کاملComplete ( O 7 , O 8 ) contribution to B̄ → X s γ at O ( α 2 s )
We calculate the set of O(αs) corrections to the branching ratio and to the photon energy spectrum of the decay process B̄ → Xsγ originating from the interference of diagrams involving the electromagnetic dipole operator O7 with diagrams involving the chromomagnetic dipole operator O8. The corrections evaluated here are one of the elements needed to complete the calculations of the B̄ → Xsγ branc...
متن کاملA Lower Bound on sin 2β from Minimal Flavour Violation
We point out that there exists an absolute lower bound on sin 2β in all models with minimal flavour violation (MFV), that do not have any new operators beyond those present in the Standard Model and in which all flavour changing transitions are governed by the CKMmatrix with no new phases beyond the KM phase. This bound depends only on |Vcb|, |Vub/Vcb| and the hadronic parameters B̂K , FBd √ B̂d ...
متن کاملB̄ → X s γ after Completion of the NLO QCD Calculations Andrzej
Several years ago, Stefan Pokorski, Manfred Münz and us outlined a program for calculation of the NLO QCD corrections to the weak radiative B̄ meson decay B̄ → Xsγ. Very recently, just before the 60th birthday of Stefan Pokorski, this program has been formally completed. In the present paper, we summarize the existing results and discuss perspectives for further improvement of the accuracy of the...
متن کاملCompleting the NLO QCD calculation of B̄ → X s γ
We evaluate two-loop b → sγ matrix elements of all the four-quark operators containing no derivatives. Contrary to previous calculations, no expansion in the mass ratio mc/mb is performed, and all the possible Dirac and flavor structures are included. Consequently, we are able to provide the last item in the NLO analysis of B̄ → Xsγ that has been missing so far, namely the two-loop matrix elemen...
