Penguin diagrams in the charm sector in K+ --> pi+ nu anti-nu
J. Mondéjar, J. Rittinger
We evaluate at next-to-next-to-leading order (NNLO) the QCD corrections to the charm contribution from penguin diagrams to the decay K+ --> pi+ nu anti-nu. A NNLO calculation is al…
Adler Function, Sum Rules and Crewther Relation of Order O(alpha_s^4): the Singlet Case
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn +1
The analytic result for the singlet part of the Adler function of the vector current in a general gauge theory is presented in five-loop approximation. Comparing this result with t…
Vector Correlator in Massless QCD at Order O(alpha_s^4) and the QED beta-function at five loop
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn +1
We present a concise summary of recent results for the vector correlator in massless QCD at order , with all colour factors being given for a generic colour group.…
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…
XQuery Join Graph Isolation
T. Grust, M. Mayr, J. Rittinger
A purely relational account of the true XQuery semantics can turn any relational database system into an XQuery processor. Compiling nested expressions of the fully compositional X…
An Inflationary Fixed Point Operator in XQuery
Loredana Afanasiev, Torsten Grust, Maarten Marx +2
We introduce a controlled form of recursion in XQuery, inflationary fixed points, familiar in the context of relational databases. This imposes restrictions on the expressible type…
