QCD-enhancement of |DELTA.I| = 1/2 transitions

AuthorsPich, Antonio
Issue DateFeb-1989
CitationProceedings of the XXIV International Conference on High Energy Physics/ International Union of Pure and Applied Physics: 834-839 (1989)
AbstractThe interplay of strong interactions in AS = 1 non-leptonic weak transitions is analyzed. In addition to the known short-distance enhancement present in the |AI| = 1/2 Wilson coefficients at the leading logarithmic approximation, it is found that huge as corrections to the |AI| = 1/2 two-point functions show up at the next-to-leading order, with the appropriate sign to produce the phenomenologically required enhancement.
