Query: One-loop QCD corrected distribution in B to X+electron decays   We give an analytic formula for the double distribution of hadronic invariant
mass and charged lepton energy to one-loop order of the perturbative QCD.
Although infrared singular, this quantity is closely related to physical
observables that can be obtained thereof through proper convolution.
