Origin of the Large Perturbative Corrections to Higgs Production at Hadron Colliders
Valentin Ahrens, Thomas Becher, Matthias Neubert +1
The very large K-factor for Higgs-boson production at hadron colliders is shown to result from enhanced perturbative corrections of the form (C_Aπα_s)^n, which arise in the analyti…
A precise determination of alpha_s from LEP thrust data using effective field theory
Thomas Becher, Matthew D. Schwartz
Starting from a factorization theorem in Soft-Collinear Effective Theory, the thrust distribution in e+e- collisions is calculated including resummation of the next-to-next-to-next…
Dynamical Threshold Enhancement and Resummation in Drell-Yan Production
Thomas Becher, Matthias Neubert, Gang Xu
Partonic cross sections for the production of massive objects in hadronic collisions receive large corrections when the invariant mass of the initial-state partons is just above th…
Two-loop QED corrections to Bhabha scattering
Thomas Becher, Kirill Melnikov
We obtain a simple relation between massless and massive scattering amplitudes in gauge theories in the limit where all kinematic invariants are large compared to particle masses.…
Analysis of Br(B-->X_s gamma) at NNLO with a Cut on Photon Energy
Thomas Becher, Matthias Neubert
By combining a recent estimate of the total B-->X_s gamma branching fraction at O(alpha_s^2) with a detailed analysis of the effects of a cut E_gamma>1.6GeV on photon energy, a pre…
Threshold Resummation in Momentum Space from Effective Field Theory
Thomas Becher, Matthias Neubert
Methods from soft-collinear effective theory are used to perform the threshold resummation of Sudakov logarithms for the deep-inelastic structure function F_2(x,Q^2) in the endpoin…
