Yukawa coupling and anomalous magnetic moment of the muon: an update for the LHC era
Andreas Crivellin, Jennifer Girrbach, Ulrich Nierste
We study the interplay between a soft muon Yukawa coupling generated radiatively with the trilinear A-terms of the minimal supersymmetric standard model (MSSM) and the anomalous ma…
Updated Predictions for Higgs Production at the Tevatron and the LHC
Valentin Ahrens, Thomas Becher, Matthias Neubert +1
We present updated predictions for the total cross section for Higgs boson production through gluon fusion at hadron colliders. In addition to renormalization-group improvement at…
On the pion decay constant
J. Gasser, G. R. S. Zarnauskas
The pion decay constant f_pi plays a crucial role in many areas of low energy particle physics. Its value may e.g. be deduced from experimental data on leptonic pion decays. Here,…
The gluon jet function at two-loop order
Thomas Becher, Guido Bell
The inclusive gluon jet function is evaluated at two-loop accuracy. This function is relevant for resummations of large perturbative logarithms in collider processes involving low-…
Drell-Yan production at small q_T, transverse parton distributions and the collinear anomaly
Thomas Becher, Matthias Neubert
Using methods from effective field theory, an exact all-order expression for the Drell-Yan cross section at small transverse momentum is derived directly in q_T space, in which all…
Electroweak Sudakov Logarithms and Real Gauge-Boson Radiation in the TeV Region
G. Bell, J. H. Kuhn, J. Rittinger
Electroweak radiative corrections give rise to large negative, double-logarithmically enhanced corrections in the TeV region. These are partly compensated by real radiation and, mo…
