Rays to renormalizations

Perturbative renormalizations of anyon quantum mechanics.

In bosonic end perturbative calculations for quantum mechanical anyon systems a regularization and renormalization procedure, analogous to those used in eld theory, is necessary. I examine the reliability and the physical interpretation of the most commonly used bosonic end regularization procedures. I then use the regularization procedure with the most transparent physical interpretation to de...

Gauge theory renormalizations from the open bosonic string

We present a unified point of view on the different methods available in the literature to extract gauge theory renormalization constants from the lowenergy limit of string theory. The Bern-Kosower method, based on an off-shell continuation of string theory amplitudes, and the construction of low-energy string theory effective actions for gauge particles, can both be understood in terms of stri...

Volume and Area Renormalizations for Conformally Compact Einstein Metrics

Renormalizations in softly broken N=1 theories: Slavnov–Taylor identities

Slavnov–Taylor identities have been applied to perform explicitly the renormalization procedure for the softly broken N=1 SYM. The result is in accordance with the previous results obtained at the level of supergraph technique.

Renormalizations and Point Δ-interactions for Coulomb Potential

In the paper the one-dimensional one-center scattering problem with the initial potential α|x|−1 on the whole axis is treated and reduced to the search for allowable self-adjoint extensions. Using the laws of conservation as necessary conditions in the singular point alongside with account of the analytical structure of fundamental solutions, it allows us to receive exact expressions for the wa...
