On the stress tensor of conformal field theories in higher dimensions
Nuclear Physics B, 1989 Abstract The behaviour of the stress tensor under conformal transformations of both flat and curved spaces is investigated for free theories in a classical background metric. In flat space ℝ d it is derived by the operator product expansion of two stress tensors.

Internal symmetries from field theories in higher dimensions
Czechoslovak Journal of Physics, 1982 It is suggested that a dynamical space-time symmetry group of a given non-linear relativistic theory is able to generate an internal symmetry group. It is shown that onlyO(2N-1, 1) andO(2N, 1) groups are admitted as simple dynamical symmetry groups, and they implyU(2 N −2) as the largest internal symmetry groups.

Further studies in aesthetic field theory V; higher dimensions
International Journal of Theoretical Physics, 1974 We consider higher dimensional universes in which the universe is constructed from four-dimensional subuniverses. Independent parameters are introduced for the subuniverses. We then consider a small coupling between the subuniverses. Emphasis is placed on the eight-dimensional case. We find that the trends from the computer are in line with the natural

A Model for Spacetime II. The Emergence of Higher Dimensions and Field Theory/Strings Dualities
Foundations of Physics, 2006 We show that in 4-spacetime modified at very short distances due to the weakening of classical logic, the higher dimensions emerge. We analyse the case of some smooth topoi, and the case of some class of pointless topoi. The pointless topoi raise the dimensionality due to the forcing adding “string” objects and thus replacing classical points in ...

Higher order coupled cluster approximation to the vacuum of
Physical Review D, 1994 The [ital S][sub 6] approximation of the coupled cluster method is applied to the vacuum state, energy, and field expectation value of [Phi][sup 4] field theory in 1+1 dimensions. Depending on the quantities considered the results show good to excellent convergence.

, 2005 As a first approach to the study of classical solutions for gauge theories in dimensions higher than four we study linear relations among the fields which ensure the equation of motion as a consequence of the Bianchi identities. We show how these relations can be obtained as integrability conditions on linear covariant first order equations.

Exploring Fractal Quantum Field Theory in Higher-Order Dimensions Using the McGinty Equation
International Journal of Theoretical & Computational PhysicsThis hypothesis investigates the application of the McGinty Equation to quantum fields in higher-order dimensions, proposing that these fields exhibit self-similar fractal properties. The primary objective is to understand the implications of fractal geometry on quantum field interactions, coupling constants, and particle scattering processes, offering

Effective field theories and higher-dimension operators
Physical Review D, 1981The contribution of heavy fermions (muons) to the electron anomalous moment in quantum electrodynamics is considered within the context of effective field theories, correct to order ..cap alpha../sup 2/m/sup 2//M/sup 2/. Although no violation of decoupling is found, it is shown that the leading contribution of the muon to the electron magnetic moment ...
