Invariant measure in hot gauge theories 1
We investigate properties of the invariant measure for the A0 gauge field in finite temperature gauge theories both on the lattice and in the continuum theory. We have found the cancellation of the naive measure in both cases. The result is quite general and holds at any finite temperature. We demonstrate, however, that there is no cancellation at any temperature for the invariant measure contr...
متن کاملString Theory in Lorentz-invariant Light Cone Gauge
Quantization of 4-dimensional Nambu-Goto theory of open string in light cone gauge, related in Lorentz-invariant way with the world sheet, is performed. Obtained quantum theory has no anomalies in Lorentz group. Determined spin-mass spectra of the theory have Regge-like behavior and do not contain the tachyon. Vertex operators of interaction theory, acting in the physical subspace, are construc...
متن کاملA New Gauge-Invariant Regularization Scheme Based on Lorentz-Invariant Noncommutative Quantum Field Theory
The IR/UV mixing in the non-commutative (NC) field theory is investigated in CarlsonCarone-Zobin (CCZ) formalism of Lorentz-invariant NC field theory provided that the fields are ‘independent’ of the ‘internal’ coordinates θ . A new regularization scheme called NC regularization is then proposed, which removes the Lorentz-invariant IR singularity by subtraction from the theory. It requires the ...
متن کاملA Note on Invariant Measure on the Local Gauge Group
In this paper we investigate the problem of the existence of invariant measures on the local gauge group. We prove that it is impossible to define a finite translationally invariant measure on the local gauge group C∞(Rn, G)(where G is an arbitrary matrix Lie group). Functional integral over the local gauge group is a commonly employed technique in the study of gauge field theories. Its earlies...
متن کاملGauge and Lorentz invariant one - pion exchange currents in electron scattering from a relativistic Fermi gas
A consistent analysis of relativistic pionic correlations and meson-exchange currents for electroweak quasielastic electron scattering from nuclei is carried out. Fully-relativistic one-pion-exchange electromagnetic operators are developed for use in one-particle emission electronuclear reactions within the context of the relativistic Fermi gas model. Then the exchange and pionic correlation cu...
