O ( α s a ) matching coefficients for axial vector current and ∆ B = 2 operator ∗
نویسندگان
چکیده
We present a calculation of the perturbative matching coefficients including mixing with higher dimensional operators for the temporal component of the heavy-light axial current, A4, and the ∆B = 2 operator, OS. For A static, NRQCD 4 , calculations with various RG-improved gauge actions are peformed. Matching coefficients with NRQCD and heavy-clover actions are also compared.

B Meson Decay Constants From NRQCD
We present quenched results for B meson decay constants using NRQCD b quarks and O(a) tadpole improved clover light quarks. For the first time, one-loop matching factors between lattice and continuum currents are incorporated through O(α/M) taking operator mixing fully into account. This includes an important O(α a) discretization correction to the heavy-light axial vector current. We find f B ...
متن کاملMatching coefficients for α s and m b to O ( α 2 s ) in the MSSM
We compute the exact two-loop matching coefficients for the strong coupling constant αs and the bottom-quark mass mb within the Minimal Supersymmetric Standard Model (MSSM), taking into account O(αs) contributions from Supersymmetric Quantum Chromodynamics (SQCD). We find that the explicit mass pattern of the supersymmetric particles has a significant impact on the predictions of αs and mb at h...
متن کاملB Meson Decay Constants Using NRQCD
Recent results for B meson decay constants with NRQCD b-quarks and clover light quarks are discussed. Perturbative matching factors through O(α/M) are now available and incorporated into the analyses. An O(α a) improvement term to the heavy-light axial current is identified and included. The slope of fP S √ MP S versus 1/MP S is significantly reduced by these corrections.
متن کاملNon-perturbative renormalization of the static vector current and its O(a)-improvement in quenched QCD LPHA
We carry out the renormalization and the Symanzik O(a)-improvement programme for the static vector current in quenched lattice QCD. The scale independent ratio of the renormalization constants of the static vector and axial currents is obtained non-perturbatively from an axial Ward identity with Wilson-type light quarks and various lattice discretizations of the static action. The improvement c...
متن کاملVector and Axial - Vector Current Correlators within the Instanton Model of Qcd Vacuum
The pion electric polarizability, α E π ± , the leading order hadronic contribution to the muon anomalous magnetic moment, a hvp(1) µ , and the ratio of the difference to the sum of vector and axial-vector correlators, (V − A)/(V + A), are found within the instanton model of QCD vacuum. The results are compared with phenomenological estimates of these quantities following from the ALEPH and OPA...
