Renormalizability of the massive Yang-Mills theory
It is shown that the massive Yang-Mills theory is on mass-shell
renormalizable. Thus the Standard Model of electroweak interactions can be
modified by removing terms with the scalar field from the Lagrangian in the
unitary gauge. The resulting electroweak theory without the Higgs particle is
on mass-shell renormalizable and unitary.Comment: 9 page
The Mellin moments of deep inelastic structure functions at two loops
We perform the analytic calculation of the Mellin moments of the structure
functions F_2 and F_L in perturbative QCD up to second order corrections and in
leading twist approximation. We calculate the 2-loop contributions to the
anomalous dimensions of the singlet and non-singlet operator matrix elements
and the 2-loop coefficient functions of F_2 and F_L. Our results are in
agreement with earlier calculations in the literature.Comment: 4 pages LaTeX, talk given at the QCD 99 Euroconference, Montpellier
