Torsion, Dilaton and Gauge Couplings
Non-Abelian gauge fields are traditionally not coupled to torsion due to violation of gauge invariance. However, it is possible to couple torsion to Yang-Mills fields while maintaining gauge invariance provided one accepts that the gauge couplings then become scalar fields. In the past this has been untenable from experimental constraints at the current epoch for the electromagnetic field at le...
متن کاملThe Vacuum Functional at Large Distances
For fields that vary slowly on the scale of the lightest mass the logarithm of the vacuum functional can be expanded as a sum of local functionals, however this does not satisfy the obvious form of the Schrödinger equation. For φ4 theory we construct the appropriate equation that this expansion does satisfy. This reduces the eigenvalue problem for the Hamiltonian to a set of algebraic equations...
متن کاملThe strong coupling constant at large distances
In this paper we discuss effective strong coupling constants. Those are well behaved in the low-Q2 domain, contrarily to αs from pQCD. We present an extraction of an effective strong coupling constant from Jefferson Lab polarized data at intermediate and low Q2. We also show how these data, together with spin sum rules, allow us to obtain the effective coupling constant over the entire Q2 range...
متن کاملLaws Governing Isolated Horizons: Inclusion of Dilaton Couplings
Mechanics of non-rotating black holes was recently generalized by replacing the static event horizons used in standard treatments with ‘isolated horizons.’ This framework is extended to incorporate dilaton couplings. Since there can be gravitational and matter radiation outside isolated horizons, now the fundamental parameters of the horizon, used in mechanics, must be defined using only the lo...
متن کاملWhat Can We Learn from QED at Large Couplings?
In order to understand QCD at the energies relevant to hadronic physics one requires analytical methods for dealing with relativistic gauge field theories at large couplings. Strongly coupled quenched QED provides an ideal laboratory for the development of such techniques, in particular as many calculations suggest that – like QCD – this theory has a phase with broken chiral symmetry. In this t...
