Title: | QCD corrections to inclusive ΔS = 1, 2 transitions at the next-to-leading order |
Authors: | Jamin, Matthias; Pich, Antonio CSIC ORCID | Issue Date: | 22-Aug-1994 | Publisher: | Elsevier | Citation: | Nuclear Physics B 425(1-2): 15-38 (1994) | Abstract: | The two-point functions for ΔS = 1 current-current and QCD-penguin operators, as well as for the ΔS = 2 operator, are calculated at the next-to-leading order. The calculation is performed in two different renormalization schemes for γ5, and the compatibility of the results obtained in the two schemes is verified. The scale- and scheme-invariant combinations of spectral two-point functions and corresponding Wilson coefficients are constructed and analyzed. For ΔS = 1, the QCD corrections to the CP-conserving part, dominated by current-current operators, are 40–120% at q2 = (1–3 GeV)2, whereas the corrections to the imaginary part, mainly coming from the penguin operator Q6, are 100–240%. The large size of the gluonic corrections to current-current operators provides a qualitative understanding of the observed enhancement of ΔI = 1/2 transitions. In the ΔS = 2 sector the QCD corrections are quite moderate (≈−20%). | Description: | 24 páginas, 3 figuras, 2 tablas.-- arXiv:hep-ph/9402363v1 | Publisher version (URL): | http://dx.doi.org/10.1016/0550-3213(94)90171-6 | URI: | http://hdl.handle.net/10261/33299 | DOI: | 10.1016/0550-3213(94)90171-6 | ISSN: | 0550-3213 |
