Meson propagators in spontaneously broken gauge theories
Hung Cheng, S. P. Li
Contrary to common belief, the longitudinal vector meson and scalar meson propagators have very different forms in spontaneously broken gauge theories. We choose the Abelian-Higgs…
Is the Standard Model Renormalizable?
Hung Cheng, S. P. Li
In this paper, we study the renormalizability of the Standard Model in the Landau gauge. On the basis of the Ward-Takahashi identities, we derive exact expressions for the physical…
The Standard Model in the Alpha gauge is not renormalizable
Hung Cheng, S. P. Li
We study the Ward-Takahashi identities in the standard model with the gauge fixing terms given by (1.1) and (1.2). We find that the isolated singularities of the propagators for th…
Physical masses and the vacuum expectation value of the Higgs field
Hung Cheng, S. P. Li
By using the Ward-Takahashi identities in the Landau gauge, we derive exact relations between particle masses and the vacuum expectation value of the Higgs field in the Abelian gau…
