The Fermion Generations Problem in the Gust in the Free World-Sheet Fermion Formulation

A. A. Maslikov, I. A. Naumov, G. G. Volkov

In the framework of the four dimensional heterotic superstring with free fermions we present a revised version of the rank eight Grand Unified String Theories (GUST) which contain…

Time evolution and observables in constrained systems

Petr Hajicek

The discussion is limited to first-class parametrized systems, where the definition of time evolution and observables is not trivial, and to finite dimensional systems in order tha…

CP Violation in Heavy Neutrino Mediated $e^{-} e^{-} \to W^{-} W^{-}$

B. Ananthanarayan, P. Minkowski

We consider the reaction $e^{-} e^{-} \to W^{-} W^{-}$ mediated by possible heavy neutrino exchange at future LINAC energies of $s >> 2 m_{W}$ . This reaction is sensitive to CP…

Fixed Point Action and Topology in the CP^3 Model

Rudolf Burkhalter

We define a fixed point action in two-dimensional lattice $CP^{N - 1}$ models. The fixed point action is a classical perfect lattice action, which is expected to show strongly…

Elastic $π π$ scattering to two loops

J. Bijnens, G. Colangelo, G. Ecker +2

We evaluate analytically the elastic $π π$ scattering amplitude to two loops in chiral perturbation theory and give numerical values for the two $S$ --wave scattering lengths and for…

Perennials and the Group-Theoretical Quantization of a Parametrized Scalar Field on a Curved Background

P. Hajicek, C. J. Isham

The perennial formalism is applied to the real, massive Klein-Gordon field on a globally-hyperbolic background space-time with compact Cauchy hypersurfaces. The parametrized form o…
