Low energy moments of heavy quark current correlators at four loops
A. Maier, P. Maierhoefer, P. Marquard +1
We describe several techniques for the calculation of multi-loop integrals and their application to heavy quark current correlators. As new results, we present the four-loop correc…
Quark and gluon form factors to three loops
P. A. Baikov, K. G. Chetyrkin, A. V. Smirnov +2
We compute the form factors of the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons to three-loop order within massless perturbative Quantum…
Polarizing a stored proton beam by spin flip?
D. Oellers, L. Barion, S. Barsov +66
We discuss polarizing a proton beam in a storage ring, either by selective removal or by spin flip of the stored ions. Prompted by recent, conflicting calculations, we have carried…
On the Resolution of Singularities of Multiple Mellin-Barnes Integrals
A. V. Smirnov, V. A. Smirnov
One of the two existing strategies of resolving singularities of multifold Mellin-Barnes integrals in the dimensional regularization parameter, or a parameter of the analytic regul…
Feynman Integral Evaluation by a Sector decomposiTion Approach (FIESTA)
A. V. Smirnov, M. N. Tentyukov
Up to the moment there are two known algorithms of sector decomposition: an original private algorithm of Binoth and Heinrich and an algorithm made public lastyear by Bogner and We…
On the reduction of Feynman integrals to master integrals
A. V. Smirnov, V. A. Smirnov
The reduction of Feynman integrals to master integrals is an algebraic problem that requires algorithmic approaches at the modern level of calculations. Straightforward application…
