On the power counting of loop diagrams in general relativity

J. F. Donoghue, T. Torma

A class of loop diagrams in general relativity appears to have a behavior which would upset the utility of the energy expansion for quantum effects. We show through the study of sp…

Is $B \to X_{s} γ$ equal to $b \to s γ$ ? Spectator contributions to rare inclusive B decays

John F. Donoghue, Alexey A. Petrov

In $B \to X_{s} γ$ there are perturbative $QC D$ corrections at order $α_{s}$ not only to the single quark line process $b \to s γ$ but also coming from a set of diagrams where the wea…
