On the Perturbative Quantization of Einstein-Hilbert Gravity Embedded in a Higher Derivative Model II
Steffen Pottel, Klaus Sibold
In a previous paper we presented the renormalization of Einstein-Hilbert gravity under inclusion of higher derivative terms and proposed a projection down to the physical state spa…
On the Perturbative Quantization of Einstein-Hilbert Gravity Embedded in a Higher Derivative Model
Steffen Pottel, Klaus Sibold
In a perturbative approach Einstein-Hilbert gravity is quantized about a flat background. In order to render the model power counting renormalizable, higher order curvature terms a…
Conjugate variables in quantum field theory and a refinement of Paulis theorem
Steffen Pottel, Klaus Sibold
For the case of spin zero we construct conjugate pairs of operators on Fock space. On states multiplied by polarization vectors coordinate operators Q conjugate to the momentum ope…
Conjugate variables in quantum field theory: the basic case
Klaus Sibold, Gautier Solard
Within standard quantum field theory of one scalar field we define operators conjugate to the energy-momentum operators of the theory. They are singled out by calculational simplic…
Conformal transformations of the S-matrix; -function identifies change of spacetime
S. Pottel, K. Sibold
First conformal transformations of the -matrix are derived in massless -theory. Then it is shown that the anomalous transformations can be rewritten as a symmetry once one…
Quantized equations of motion in non-commutative theories
Paul Heslop, Klaus Sibold
Quantum field theories based on interactions which contain the Moyal star product suffer, in the general case when time does not commute with space, from several diseases: quantum…
