Analysis of the photon spectrum in inclusive B --> X$_{s}\gamma$ decays
Using a combination of the operator product and heavy quark expansions we resum the leading nonperturbative contributions to the inclusive photon spectrum in $B\to X_s\,\gamma$ decays. The shape of the spectrum is determined by a structure function, which describes the distribution of the light-cone...
