Two-Loop Correction to Bhabha Scattering
Z. Bern, L. Dixon, A. Ghinculov
We present the two-loop virtual QED corrections to e^+ e^- to mu^+ mu^- and Bhabha scattering in dimensional regularization. The results are expressed in terms of polylogarithms. T…
Exact non-factorizable O(alpha_s g^2) two-loop contribution to Z -> b bbar
Adrian Ghinculov, York-Peng Yao
For Z -> b bbar, we calculate all the two-loop top dependent Feynman graphs, which have mixed QCD and electroweak contributions that are not factorizable. For evaluating the graphs…
Electroweak Physics
G. Azuelos, U. Baur, J. van der Bij +47
We review the prospects for studies in electroweak physics at the LHC.
Muon colliders and the non-perturbative dynamics of the Higgs boson
Adrian Ghinculov, Thomas Binoth
A muon collider operating in the TeV energy range can be an ideal s-channel Higgs boson factory. This is especially true for a heavy Higgs boson. The non-perturbative dynamical asp…
Exact O(g^2 alpha_s) top decay width from general massive two-loop integrals
Adrian Ghinculov, York-Peng Yao
We calculate the b-dependent self-energy of the top quark at O(g^2 α_s) by using a general massive two-loop algorithm proposed in a previous article. From this we derive by unitari…
