چکیده
We compute the four-loop corrections to Higgs-bottom vertex within massless QCD and present analytic results for all color structures. The infrared poles of renormalized form factor agree with predicted pattern. Furthermore, we use Higgs-bottom, photon-quark, Higgs-gluon factors provide hard matching coefficients in soft-collinear effective theory up accuracy.

Two-Loop Matching Coefficients for Heavy Quark Currents
In this paper we consider the matching coefficients up to two loops between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) for the vector, axial-vector, scalar and pseudo-scalar currents. The structure of the effective theory is discussed and analytical results are presented. Particular emphasis is put on the singlet diagrams. PACS numbers: In the recent years quite a lot of acti...
متن کاملMatching QCD and HQET heavy – light currents at two loops and beyond
Heavy–light QCD currents are matched with HQET currents at two loops and leading order in 1/m. A single formula applies to all current matchings. As a by–product, a master formula for the two–loop anomalous dimension of the QCD current q̄γ1 . . . γnq is obtained, yielding a new result for the tensor current. The dependence of matching coefficients on γ5 prescriptions is elucidated. Ratios of QCD...
متن کاملDecays at NNLO in SCET
We compute NNLO (O(α2 s)) corrections to the hard-scattering kernels entering the QCD factorization formula for B → V γ decays, where V is a light vector meson. We give complete NNLO results for the dipole operators Q7 and Q8, and partial results for Q1 valid in the large-β0 limit and neglecting the NNLO correction from hard spectator scattering. Large perturbative logarithms in the hard-scatte...
متن کاملMatching QCD and HQET at three loops
QCD problems with a single heavy quarkQ can be treated in a simpler effective theory — HQET, if there exists a 4-velocity v such that the heavyquark momentum is p = mv+k (m is the on-shell mass) and the characteristic residual momentum is small: k ≪ m. QCD operators can be written as series in 1/m via HQET operators; the coefficients in these series are determined by matching on-shell matrix el...
متن کاملQCD Decoupling at Four Loops s
We present the matching condition for the strong coupling con-tant α (n f) s at a heavy quark threshold to four loops in the modified minimal subtraction scheme. Our results lead to further decrease of the theoretical uncertainty of the evolution of the strong coupling constant through heavy quark thresholds. Using a low energy theorem we furthermore derive the effective coupling of the Higgs b...
