Halpern-Huang directions in effective scalar field theory
Vipul Periwal
Halpern and Huang recently showed that there are relevant directions in the space of interactions at the Gaussian fixed point. I show that their result can be derived from Polchins…
Unitary theory of massive non-Abelian vector bosons
Vipul Periwal
This paper is being revised to make it intelligible, and to incorporate some corrections.
Infrared regularization of non-Abelian gauge theories
Vipul Periwal
Curci and Ferrari found a unique BRS-invariant action for non-Abelian gauge theories which includes a mass term for the gauge bosons. I analyze this action. While the BRS operator…
Anisotropy beta functions
Vipul Periwal
The flow of couplings under anisotropic scaling of momenta is computed in theory in 6 dimensions. It is shown that the coupling decreases as momenta of two of the particles b…
Improving lattice perturbation theory
Vipul Periwal
Lepage and Mackenzie have shown that tadpole renormalization and systematic improvement of lattice perturbation theory can lead to much improved numerical results in lattice gauge…
Dimensional continuation without perturbation theory
Vipul Periwal
A formula is proposed for continuing physical correlation functions to non-integer numbers of dimensions, expressing them as infinite weighted sums over the same correlation functi…
