Semi-Leptonic b-decay at Intermediate Recoil
Matthew Dowling, Alexey Pak, Andrzej Czarnecki
We compute the O(α_s^2) corrections to the differential rate of the semileptonic decay b -> clv at the "intermediate recoil" point, where the c-quark mass and the invariant mass of…
Semileptonic decays in the limit of a heavy daughter quark
Matthew Dowling, Jan H. Piclum, Andrzej Czarnecki
The rate of the semileptonic decay b to c l v is calculated with order alphas^2 accuracy, as an expansion around the limit of equal masses of the b and c quarks. Recent results obt…
Mass effects in muon and semileptonic b -> c decays
Alexey Pak, Andrzej Czarnecki
Quantum chromodynamics (QCD) effects in the semileptonic decay b -> c l nu are evaluated to the second order in the coupling constant, O(alpha_s^2), and to several orders in the ex…
Positronium-ion decay
Mariusz Puchalski, Andrzej Czarnecki, Savely G. Karshenboim
We present a precise theoretical prediction for the decay width of the bound state of two electrons and a positron (a negative positronium ion), Gamma(Ps^-) = 2.087 085(12)/ns. We…
Electroweak Radiative Corrections to Muon Capture
A. Czarnecki, W. J. Marciano, A. Sirlin
Electroweak radiative corrections to muon capture on nuclei are computed and found to be sizable. They enhance the capture rates for hydrogen and helium by 2.8% and 3.0% respective…
Theoretical Summary of Moriond 2004: QCD and Hadronic Interactions
Andrzej Czarnecki
Theoretical talks and discussions at Rencontres de Moriond 2004 "QCD and Hadronic Interactions" are summarized. Following exciting recent experimental discoveries, theoretical deve…
