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
Renormalizable and unitary Lorentz invariant model of quantum gravity
We analyze the R + R2 model of quantum gravity where terms quadratic in the
curvature tensor are added to the General Relativity action. This model was
recently proved to be a self-consistent quantum theory of gravitation, being
both renormalizable and unitary. The model can be made practically
indistinguishable from General Relativity at astrophysical and cosmological
scales by the proper choice of parameters.Comment: 12 page
