P-wave contribution to third-order top-quark pair production near threshold
M. Beneke, J. Piclum, T. Rauh
The next-to-leading order (NLO) P-wave Coulomb Green function contributes at third-order to top-pair production in e+ e- collisions near threshold. In this paper we compute the NLO…
Non-relativistic pair annihilation of nearly mass degenerate neutralinos and charginos I. General framework and S-wave annihilation
M. Beneke, C. Hellmann, P. Ruiz-Femenia
We compute analytically the tree-level annihilation rates of a collection of non-relativistic neutralino and chargino two-particle states in the general MSSM, including the previou…
Non-local Higgs actions: Tree-level electroweak constraints and high-energy unitarity
M. Beneke, P. Knechtges, A. Mück
We consider electroweak symmetry breaking by a certain class of non-local Higgs sectors. Extending previous studies employing the Mandelstam condition, a straight Wilson line is us…
NNNLO results on top-quark pair production near threshold
M. Beneke, Y. Kiyo, K. Schuller
We present new results on the NNNLO top-antitop production cross section near threshold from potential and ultrasoft gluon corrections. The new non-logarithmic third-order terms ar…
Third-order non-Coulomb correction to the S-wave quarkonium wave functions at the origin
M. Beneke, Y. Kiyo, K. Schuller
We compute the third-order correction to the S-wave quarkonium wave functions |ψ_n(0)|^2 at the origin from non-Coulomb potentials in the effective non-relativistic Lagrangian. Tog…
Exclusive non-leptonic B meson decays from QCD
M. Beneke
A brief report on the QCD factorization approach to exclusive B decays and its applications is presented. In an appendix a subtle issue concerning partial integration in the parame…
