Generalized variational procedure: An application to non-perturbative QCD
Osvaldo Civitarese, Peter Otto Hess, Davis Arturo Amor-Quiroz
We present a generalized variational procedure oriented to the algebraic solution of many body Hamiltonians expressed in bosonic and fermionic variables. The method specializes in…
Pseudo-Complex Field Theory
Peter O. Hess, Walter Greiner
A new formulation of field theory is presented, based on a pseudo-complex description. An extended group structure is introduced, implying a minimal scalar length, rendering the th…
Extending the GKZ limit without breaking Lorentz Invariance
P. O. Hess, W. Greiner
A scenario is presented on how to shift the predicted cutoff in the cosmic ray spectrum at 10**20 eV, called the Greisen-Zatsepin-Kuzmin limit (GKZ), to larger energies without bre…
Dimensional Reduction, Hard Thermal Loops and the Renormalization Group
C. R. Stephens, Axel Weber, Peter O. Hess +1
We study the realization of dimensional reduction and the validity of the hard thermal loop expansion for lambda phi^4 theory at finite temperature, using an environmentally friend…
Bound States from Regge Trajectories in a Scalar Model
A. Weber, J. C. Lopez Vieyra, C. R. Stephens +2
The calculation of bound state properties using renormalization group techniques to compute the corresponding Regge trajectories is presented. In particular, we investigate the bou…
Quantum Field Theory in the Limit x << 1
C. R. Stephens, A. Weber, J. C. Lopez Vieyra +1
The asymptotic high momentum behaviour of quantum field theories with cubic interactions is investigated using renormalization group techniques in the asymmetric limit x << 1. Part…
