Título : QCD-enhancement of |DELTA.I| = 1/2 transitions
Autor : Pich, Antonio
Fecha de publicación : Feb-1989
Editor: Springer
Resumen: The 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.
