Higher-Order Corrections to QCD Factorization in B → πK, ππ Decays
The renormalon calculus is used to calculate the terms of order β 0 α n s in the perturbative expansions of the Wilson coefficients and hard-scattering kernels entering the QCD factorization formula for hadronic B-meson decays into two light pseudoscalar mesons. The asymptotic behavior of the expansions is analyzed, and a minimal model of power corrections arising from soft “non-factorizable” g...
متن کاملHigher Order Qcd Corrections in Exclusive Charmless B Decays
We discuss exclusive charmless B decays within the Standard Model of particle physics. These decays play a central role in the on-going process to constrain the parameters of the CKM matrix and to clarify the nature of CP violation. In order to exploit the rich source of data that is currently being collected at the experiments, a systematic theoretical treatment of the complicated hadronic dyn...
متن کاملHigher-order Corrections to Higgs-boson Decays *
One of the great puzzles of elementary particle physics today is whether nature makes use of the Higgs mechanism of spontaneous symmetry breaking to generate the observed particle masses. The Higgs boson, H , is the missing link sought to verify this concept in the Standard Model. Many of the properties of the Higgs boson are fixed, e.g., its couplings to the gauge bosons, gV VH = 2 G 1/2 F M 2...
متن کاملB?J/?(?,K) Decays within QCD Factorization Approach
We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...
متن کاملHigher-order Qcd Corrections to Γ
In the study of scattering phenomena in the limit of very large energies at fixed momentum transfer, one must face the fact that the two most promising probes of BFKL physics, namely smallx effects in DIS and large-rapidity-gap events in dijet production at hadron colliders, are inherently dependent upon long-distance physics, due to the presence of hadrons in the initial state; this poses seri...
