Penguin diagrams in the charm sector in K+ --> pi+ nu anti-nu
J. Mondéjar, J. Rittinger
We evaluate at next-to-next-to-leading order (NNLO) the QCD corrections to the charm contribution from penguin diagrams to the decay K+ --> pi+ nu anti-nu. A NNLO calculation is al…
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…
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.
Radiative-nonrecoil corrections of order alpha^2 (Z alpha)^5 to the Lamb shift
Matthew Dowling, Jorge Mondejar, Jan H. Piclum +1
We present results for the corrections of order alpha^2 (Z alpha)^5 to the Lamb shift. We compute all the contributing Feynman diagrams in dimensional regularization and a general…
Effective lagrangians for light-light interaction with a background field
Jorge Mondejar
We address the issue of light-light scattering in the presence of a background field at low energies using effective lagrangians. We derive the Euler-Heisenberg lagrangian at one l…
