Results of the O ( α s ) two - loop virtual corrections to B → X s l + l − in the standard model
We present the results of the O(αs) two-loop virtual corrections to the differential decay width dΓ(B → Xsll)/dŝ, where ŝ is the invariant mass squared of the lepton pair, normalized to m b . Those contributions from gluon bremsstrahlung which are needed to cancel infrared and collinear singularities are also included. Our calculation is restricted to the range 0.05 ≤ ŝ ≤ 0.25 where the effects...
متن کاملQCD Corrections to the Decay B → X s l + l −
We briefly discuss the status of the NNLL QCD calculations in the inclusive rare B decay B → Xsll. Two important ingredients, the two-loop matrix elements of the four quark operator O2 and the bremsstrahlung contributions, were quite recently finalised. The new contributions significantly improve the sensitivity of the inclusive decay B → Xsll decay in testing extensions of the standard model i...
متن کاملAnalytic two–loop virtual corrections to b → dll
We compute the two–loop virtual corrections to the flavour changing neutral current process b → dl+l−. As calculation techniques integration by parts identities and the method of differential equations are used. The result is presented in closed form as a function of q/mb , where q 2 is the invariant mass of the lepton pair and mb is the b–quark mass.
متن کاملVirtual O ( α s ) corrections to the inclusive decay b → sγ 1 Christoph Greub
We present in detail the calculation of the O(αs) virtual corrections to the matrix element for b → sγ. Besides the one-loop virtual corrections of the electromagnetic and color dipole operators O7 and O8, we include the important two-loop contribution of the four-Fermi operator O2. By applying the Mellin-Barnes representation to certain internal propagators, the result of the two-loop diagrams...
متن کاملVirtual O ( a . ) corrections to the inclusive decay
We present in detail the calculation of the O(as) virtual corrections to the matrix element for b + s-y. Besides the one-loop virtual corrections of the electromagnetic and color dipole operators 07 and 08, we include the important two-loop contribution of the four-Fermi operator 02. By applying the Mellin-Barnes representation to certain internal propagators, the result of the two-loop diagram...
