Two-loop QED hadronic corrections to Bhabha scattering
Johann H. Kühn, Sandro Uccirati
Theoretical predictions for Bhabha scattering at the two-loop level require the inclusion of hadronic vacuum polarization in the photon propagator. We present predictions for the c…
Four-pion production in tau decays and e+e- annihilation: an update
Henryk Czyz, Johann H. Kuhn, Agnieszka Wapienik
An improved description of four-pion production in electron-positron annihilation and in tau lepton decays is presented. The model amplitude is fitted to recent data from BaBar whi…
Hadronic Z- and tau-Decays in Order alpha_s^4
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn
Using recently developed methods for the evaluation of five-loop amplitudes in perturbative QCD, corrections of order alpha_s^4 for the cross section of electron-positron annihilat…
Top Quarks, Axigluons and Charge Asymmetries at Hadron Colliders
Oscar Antunano, Johann H. Kuhn, German Rodrigo
Axigluons are colored heavy neutral gauge boson that couple to quarks through an axial vector current and the same strong coupling as gluons. The most important model-independent m…
Electroweak corrections to hadronic production of W bosons at large transverse momenta
Johann H. Kuhn, A. Kulesza, S. Pozzorini +1
To match the precision of present and future measurements of W-boson production at hadron colliders electroweak radiative corrections must be included in the theory predictions. In…
Determination of the strong coupling constant from the CLEO measurement of the total hadronic cross section in annihilation below 10.56 GeV
Johann H. Kuhn, Matthias Steinhauser, Thomas Teubner
Using recent CLEO III results for the cross section for at seven centre-of-mass energies between 6.964 and 10.538 GeV, we derive a value for the strong c…
