Abstract
We analyze the short and long distance contributions to inclusive B --> X(d) gamma decay, paying particular attention to the dependence on the Cabibbo-Kobayashi-Maskawa parameter V-td. We discuss penguin diagrams with internal u and c quarks in the framework of the effective field theory. We also estimate the size of possible long range contributions by using vector meson dominance.File in questo prodotto:
