Magnetic moment of a bound electron
Andrzej Czarnecki, Matthew Dowling, Jorge Mondejar +1
Theoretical predictions underlying determinations of the fine structure constant alpha and the electron-to-proton mass ratio m_e/m_p are reviewed, with the emphasis on the bound el…
Radiative-nonrecoil corrections of order alpha^2 (Z alpha) E_F to the hyperfine splitting of muonium
Jorge Mondejar, Jan H. Piclum, Andrzej Czarnecki
We present results for the corrections of order alpha^2 (Z alpha) E_F to the hyperfine splitting of muonium. We compute all the contributing Feynman diagrams in dimensional regular…
Helicity fractions of W bosons from top quark decays at NNLO in QCD
Andrzej Czarnecki, Jurgen G. Korner, Jan H. Piclum
Decay rates of unpolarized top quarks into longitudinally and transversally polarized W bosons are calculated to second order in the strong coupling constant alpha_s. Including the…
Two-loop corrections to the Lamb shift
Matthew Dowling, Jorge Mondejar, Jan H. Piclum +1
We present a new calculation of the order alpha^2 (Z alpha)^5 correction to the Lamb shift, which uses methods developed for multi-loop calculations.
