چکیده
We present details of our evaluation of the NNLO QCD corrections to B(B̄ → Xsγ) in the heavy charm limit (mc ≫ mb 2 ). Results of this calculation have been essential for estimating O (α s) effects in this branching ratio via interpolation in mc.

We compute the third-order corrections to the heavy quarkonium spectrum and production/annihilation rates due to the leading renormalization group running of the static potential. The previously known complete O(m q α 5 s) result for the heavy quarkonium ground state energy is extended to the exited states. After including the O(α 3 s) corrections the perturbative results are in surprisingly go...

Deep inelastic scattering provides us with detailed information on the nucleon structure. In order to extract the parton distribution functions from DIS cross sections and to measure αs(M 2 Z) with high precision it is crucial to control the QED radiative corrections. The 1– and 2–loop leading–log QED corrections were derived in Ref. [1–3]. Complete 1-loop corrections for DIS were given in Refs...
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 کاملNNLO QCD Corrections to the B̄ → X s γ Matrix Elements Using Interpolation in m c
One of the most troublesome contributions to the NNLO QCD corrections to B̄ → Xsγ originates from three-loop matrix elements of four-quark operators. A part of this contribution that is proportional to the QCD beta-function coefficient β0 was found in 2003 as an expansion in mc/mb. In the present paper, we evaluate the asymptotic behaviour of the complete contribution for mc ≫ mb/2. The asymptot...
