Some infinite series related to Feynman diagrams
Odd Magne Ogreid, Per Osland
Results are presented for some infinite series appearing in Feynman diagram calculations, many of which are similar to the Euler series. These include both one-, two- and three-dim…
Critical Phenomenon of a Consistent q-Deformed Squeezed State
Per Osland, Jian-zu Zhang
Within a self-consistent framework of q-deformed Heisenberg algebra and its equivalent framework of q-deformed boson commutation relations, which relate to the under-cutting phenom…
One-loop results for the quark-gluon vertex in arbitrary dimension
A. I. Davydychev, P. Osland, L. Saks
Results on the one-loop quark-gluon vertex with massive quarks are reviewed, in an arbitrary covariant gauge and in arbitrary space-time dimension. We show how it is possible to ge…
Quark-gluon vertex in arbitrary gauge and dimension
A. I. Davydychev, P. Osland, L. Saks
One-loop off-shell contributions to the quark-gluon vertex are calculated, in an arbitrary covariant gauge and in arbitrary space-time dimension, including quark-mass effects. It i…
Vacuum and MSW interpretations of solar neutrino data with the LNW mass matrix
Per Osland, Geir Vigdel
The Lehmann-Newton-Wu mass matrix, which was recently applied to neutrinos, is further investigated. The analytic results presented earlier are confirmed numerically for the solar…
Mikheyev-Smirnov-Wolfenstein Effect for Linear Electron Density
Harry Lehmann, Per Osland, Tai Tsun Wu
When the electron density is a linear function of distance, it is known that the MSW equations for two neutrino species can be solved in terms of known functions. It is shown here…
