Abstract:
We investigate the dependence of the contributions of interferences of the operators O1, O2 and O7 to the double differential decay width dG/(ds1ds2) for B- > Xsgg decay from the renormalization scale. Analytic expressions for all the contributions are presented, up to As order for (O7,O7) interference, and the tree level contributions for the interferences (O1,O1), (O1,O2), (O1,O7), (O2,O2), (O2,O7).
