Two-Loop Static QCD Potential for General Colour State
B. A. Kniehl, A. A. Penin, Y. Schröder +2
In this letter, we extend the known results for the QCD potential between a static quark and its antiquark by computing the two-loop corrections to the colour-octet state.
Supersymmetric Higgs production in gluon fusion at next-to-leading order
Robert V. Harlander, Matthias Steinhauser
The next-to-leading order (NLO) QCD corrections to the production and decay rate of a Higgs boson are computed within the framework of the Minimal Supersymmetric Standard Model (MS…
Heavy Quarks at Threshold: Recent Developments
Matthias Steinhauser
Recent developments in the treatment of a system of heavy quarks close to their production threshold are discussed. Particular emphasis is put on the next-to-next-to-next-to-leadin…
J/psi plus jet associated production in two-photon collisions at next-to-leading order
M. Klasen, B. A. Kniehl, L. N. Mihaila +1
We calculate the cross section of J/psi plus jet inclusive production in gamma gamma collisions at next-to-leading order within the factorization formalism of nonrelativistic quant…
Relation between bottom-quark MS-bar Yukawa coupling and pole mass
Bernd A. Kniehl, Jan H. Piclum, Matthias Steinhauser
We calculate the O(alpha alpha_s) corrections to the relationships between the MS-bar Yukawa couplings and the pole masses of the first five quark flavours in the standard model. W…
: First Next-to-Next-to-Leading Order Results
Matthias Steinhauser
In this contribution the first next-to-next-to-leading order corrections to the branching ratio are discussed. This includes the completion of the matching…
Two-loop electroweak correction of O(G_F M_t^2) to the Higgs-boson decay into photons
Frank Fugel, Bernd A. Kniehl, Matthias Steinhauser
We compute the dominant two-loop electroweak correction, of O(G_F M_t^2), to the partial width of the decay of an intermediate-mass Higgs boson into a pair of photons. We use the a…
Splitting from Nonrelativistic Renormalization Group
A. A. Penin, A. Pineda, V. A. Smirnov +1
We compute the hyperfine splitting in a heavy quarkonium composed of different flavors in next-to-leading logarithmic approximation using the nonrelativistic renormalization group.…
Three-loop matching of the dipole operators for b -> s gamma and b -> s g
Mikolaj Misiak, Matthias Steinhauser
We evaluate the three-loop matching conditions for the dimension-five operators that are relevant for the b -> s gamma decay. Our calculation completes the first out of three steps…
