Phenomenological issues in the determination of Delta Gamma(D)
D0 Δ Γ D experiments D0 decay model phase difference cleo
2014/12/22
We consider the issue of determining the D0– width difference ΔΓD experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D0 decay modes i...

Weak matrix elements no cover dispersion
2014/12/22
We reconsider the dispersive evaluation of the weak matrix elements h()I=2|Q7,8|K0i in the chiral limit. The perturbative matching is accomplished fully within the scheme dependence used in the two ...
